FRACTIONAL ORDER PID CONTROLLER TUNING BASED ON IMC IJITCA Journal
In this work, a class of fractional order controller (FOPID) is tuned based on internal model control
(IMC). This tuning rule has been obtained without any approximation of time delay. Moreover to show

uncertainty interval which results in a stable closed loop control system. For a typical system, robust
stability has been done to find maximum time constant uncertainty interval of system. Two clarify the
proposed control system design procedure, three examples have been given.

Closed-loop step response for tuning PID fractional-order filter controllersISA Interchange
Analytical methods are usually applied for tuning fractional controllers. The present paper proposes an empirical method for tuning a new type of fractional controller known as PID-Fractional-Order-Filter (FOF-PID). Indeed, the setpoint overshoot method, initially introduced by Shamsuzzoha and Skogestad, has been adapted for tuning FOF-PID controller. Based on simulations for a range of first order with time delay processes, correlations have been derived to obtain PID-FOF controller parameters similar to those obtained by the Internal Model Control (IMC) tuning rule. The setpoint overshoot method requires only one closed-loop step response experiment using a proportional controller (P-controller). To highlight the potential of this method, simulation results have been compared with those obtained with the IMC method as well as other pertinent techniques. Various case studies have also been considered. The comparison has revealed that the proposed tuning method performs as good as the IMC. Moreover, it might offer a number of advantages over the IMC tuning rule. For instance, the parameters of the frac- tional controller are directly obtained from the setpoint closed-loop response data without the need of any model of the plant to be controlled.

"America's Clean Energy Maverick: How and Why Texas Grabbed the Renewable Ene...Clean Energy Canada
Though renowned for its oil and gas resources, in recent years Texas has also emerged as a national renewable-energy leader. As a result of state and business leadership, in 2013 the politically conservative, enterprise-focussed state generated more energy from the wind than any other state, and the equivalent of half of Alberta's power supply. With a competitive electricity market similar to Alberta's, Texas has found ways to diversify its electricity mix and encourage clean energy investment.
How did a conservative, market-oriented, oil-and-gas focused jurisdiction—one with a deregulated electricity market—emerge as a national renewable energy leader? On July 15, 2014, Michael Osborne, co-founder of the Texas Renewable Energy Industry Association and one of Texas’ most prominent renewable energy pioneers, shared his take in Calgary Alberta.

Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
We have compiled the most important slides from each speaker's presentation. This year’s compilation, available for free, captures the key insights and contributions shared during the DfMAy 2024 conference.
Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECTjpsjournal1
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

2. Objectives of this lecture
In this chapter you will learn:
Iteration statements (Loop statements)
for repetition statement
while statement
do…while repetition statement
break and continue statements
Control Statements (2)— 2
4. For repetition statement (I)
General form of the for statement
for ( initialization; loopContinuationCondition; increment or decrement)
statement;
The initialization is an assignment statement that is used to set the loop
control variable.
The condition is a relational expression that determines
when the loop exits.
The increment/decrement defines how the loop control
variable changes each time the loop is repeated.
You must separate these three major sections by
semicolons.
The for loop continues to execute as long as the
condition is true.
Once the condition becomes false, program execution
resumes on the statement following the for.

Control Statements (2)— 20
22. for repetition statement (IV)
In for loops, the conditional test is always
performed at the top of the loop.
This means that the code inside the loop
may not be executed at all if the condition
is false to begin with.
Control Statements (2)— 22
23. for repetition statement (V)
for Loop Variations
One of the most common variations uses the
comma operator to allow two or more
variables to control the loop.
Example:
Control Statements (2)— 23
24. for repetition statement (VI)
The Infinite Loop with for
for loop is traditionally used for this purpose
Since none of the three expressions that form
the for loop are required, you can make an
endless loop by leaving the conditional
expression empty:
Control Statements (2)— 24
25. for repetition statement (VII)
You can exit from an infinite using break
statement
Example
Control Statements (2)— 25
26. for repetition statement (VIII)
for Loops with no Bodies
A statement may be empty
This means that the body of the for loop (or
any other loop) may also be empty.
You can use this fact to improve the efficiency
of certain algorithms and to create time delay
loops.
Example
for(i=0; i<10000; i++);
Control Statements (2)— 26
27. Good Programming Practice 5.1
Control counting loops with integer values.
Place a blank line before and after each
major control structure to make it stand out
in the program.
Control Statements (2)— 27
28. Common Programming Error 5.1
Floating-point values may be approximate,
so controlling counting loops with floating-point
variables can result in imprecise
counter values and inaccurate tests for
termination.
Control Statements (2)— 28
29. Common Programming Error 5.3
When a for structure declares its control
variable in the initialization section of the
for structure header, using the control
variable after the for structure’s body is a
compiler error.
Example:
Control Statements (2)— 29
30. Common Programming Error 5.4
Using commas in a for structure header
instead of the two required semicolons
is a syntax error.
Placing a semicolon immediately to the
right of a for structure header’s right
parenthesis makes the body of that for
structure an empty statement. This is
normally a logic error.
Control Statements (2)— 30
31. Other math operations in for portions
The initialization, loop-continuation
condition and increment or decrement
portions of a for structure can contain
arithmetic expressions.
Assume x = 2 and y = 10;
is equivalent to the statement
Control Statements (2)— 31
32. Common Programming Error 5.6
Not using the proper relational operator in
the loop-continuation condition of a loop
that counts downward (e.g., using i <= 1 in
a loop counting down to 1) is usually a
logic error that will yield incorrect results
when the program runs.
Control Statements (2)— 32
34. The while loop (I)
The second popular loop available in C/C++/C#
is the while loop.
The general form is
while(condition)
statement;

62. Another Example with while loop
Class Math include all mathematic functions.
Pow(a,b) = ab
Initialize counter variable x to 1
The condition is true (x=1<=10)
Continue looping as long as x’s value
is less than or equal to 10
Increment x by 1, which
causes x to exceed 10
eventually
Control Statements (2)— 62
66. The do-while loop (I)
Unlike for and while loops, which test the loop
condition at the top of the loop, the do-while loop
checks its condition at the bottom of the loop
This means that a do-while loop always executes
at least once.
The general form of the do-while loop is
do {
statement;
} while(condition);
Control Statements (2)— 66
67. The do-while loop (II)
Declare and initialize
control variable counter
do…while loop displays counter’s
value before testing for counter’s
Control Statements (2)— 67
69. Loop iterations
Declaring Variables within Selection and Iteration
Statements
it is possible to declare a variable within if, switch, for,
while, do..while loops
A variable declared in one of these places has its
scope limited to the block of code controlled by that
statement
/* i is local to for loop; j is known outside
loop. */
int j;
for(int i = 0; i<10; i++)
j = i * i;
/* i = 10; // *** Error *** -- i not known here!
*/
Control Statements (2)— 69
71. The return statement
The break statement
The exit() statement
The continue statement
Control Statements (2)— 71
72. The return statement
The return statement is used to return from a
function
It is categorized as a jump statement because it
causes execution to return (jump back) to the
point at which the call to the function was made.
Control Statements (2)— 72
73. The break Statement (I)
Causes immediate exit from control
structure
Used in while, for, do…while or switch
statements
The break statement has two uses:
You can use it to terminate a case in the
switch statement
You can also use it to force immediate
termination of a loop, bypassing the normal
loop conditional test
Control Statements (2)— 73
74. prints the numbers 0 through 10 on the screen. Then the loop terminates because break
causes immediate exit from the loop, overriding the conditional test t<100.
Control Statements (2)— 74
75. Programming Tip
Programmers often use the break statement
in loops in which a special condition can
cause immediate termination.
Control Statements (2)— 75
78. The continue Statement (I)
Instead of forcing termination, however, continue forces
the next iteration of the loop to take place, skipping any
code in between.
For the for loop, continue causes the conditional test
and increment portions of the loop to execute.
For the while and do-while loops, program control
passes to the conditional tests.
Control Statements (2)— 78
