Speed Control of Induction Motor using Variable Frequency DriveSandeep Kaushal
Induction motor is constant speed motor at a particular frequency and consumes almost same power irrespective of load demand. Let's talk about two different load one is high load and other low load. AT low load motor is delivering the load with some current and thereby torque is maintained. If load goes high, to maintain the same speed and developed torqued, motor will draw extra current and will corresponds to more losses. If speed of motor is reduced corresponding too low load and is increased corresponding to high load, then substantial amount of power can be saved. And speed can be changed by changing the frequency of input supply.

Implementation scheme of the Direct Torque Control strategy to Four Switch T...IJMER
This paper proposes a novel direct torque control (DTC) strategy for induction motor (IM) drives
fed by a four switch three-phase inverter (FSTPI). The introduced strategy is based on the emulation of the
operation of the conventional six switch three-phase inverter (SSTPI). This has been achieved thanks to a
suitable combination of the four unbalanced voltage vectors intrinsically generated by the FSTPI, leading to
the synthesis of the six balanced voltage vectors of the SSTPI.
This approach has been adopted in the design of the vector selection table of the proposed DTC
strategy which considers a subdivision of the Clarke plane into six sectors. Simulation results have revealed
that, thanks to the proposed DTC strategy, FSTPI-fed IM drives exhibit interesting performance. These have
been experimentally validated and compared to the ones yielded by the Takahashi and the basic DTC
strategies dedicated to the SSTPI and to the FSTPI, respectively.

Speed Control of DC Motor under Varying Load Using PID ControllerCSCJournals
DC motors are used extensively in industrial variable speed applications because of most demanding speed-torque characteristics and are simple in controlling aspects. This paper presents a DC motor speed controlling technique under varying load condition. The linear system model of separately excited DC motor with Torque-variation is designed using PID controller. A Matlab simulation of proposed system with no-Load and full-load condition is performed on Simulink platform to observe the system response. The motor speed is kept constant in this experiment. The simulation result of the experiment shows that a motor is running approximately at a constant speed regardless of a motor load. The Simulink results show that the speed of the motor is slow down only for about 270 rpm (9%) in 980 milliseconds under the effect of full load. However, the motor speed is hunting about 200 rpm (6.66%) in 900 milliseconds on unloading condition. It is concluded that a PID controller is successful tool for controlling the motor speed in presence of load disturbances.
SPEED AND TORQUE CONTROL OF AN INDUCTION MOTOR WITH ANN BASED DTCijics
Due to advantages such as fast dynamic response, simple and robust control structure, direct torque
control (DTC) is commonly used method in high performance control method for induction motors. Despite
mentioned advantages, there are some chronically disadvantages with this method like high torque and
current ripples, variable switching behaviour and control problems at low speed rates. On the other hand,
artificial neural network (ANN) based control algorithms are getting increasingly popular in recent years
due to their positive contribution to the system performance. The purpose of this paper is investigating of
the effects of ANN integrated DTC method on induction motor performance by numerical simulations. For
this purpose, two different ANN models have been designed, trained and implemented for the same DTC
model. The first ANN model was designed to select optimum inverter and the second model was designed to
use in the determination of the flux vector position. Matlab/Simulink model of the proposed ANN based
DTC method was created in order to compare with the conventional DTC and the proposed DTC methods.
The simulation studies proved that the induction motor torque ripples have been reduced remarkably with
the proposed method and this approach can be a good alternative to the conventional DTC method for
induction motor control.

Space Vector Pulse Width Modulation Schemes for Two-Level Voltage Source Inve...IDES Editor
Space Vector Pulse Width Modulation (SVPWM)
method is an advanced, computation intensive PWM method
and possibly the best among all the PWM techniques for
variable frequency drive applications. The SVPWM is an
alternative method for the determination of switching pulse
width and their position. The major advantage of SVPWM
stem from the fact that, there is a degree of freedom of space
vector placement in a switching cycle. This feature improves
the harmonic performance of this method. This method has
been finding widespread application in recent years because
of the easier digital realization and better dc bus utilization.
In this paper, three SVPWM schemes, called 7-segment space
vector modulation (SVM), 7-segment SVM with even-order
harmonic elimination and 5-segment (discontinuous) SVM
are studied in detail. The theoretical analysis, design,
switching sequence and SIMULINK implementation of these
three SVM schemes is presented in step-by-step manner

Analysis of Induction Motor Speed Control Using SCADA Based Drive Operated Sy...IJSRD
This Paper represents the analysis of induction motor speed control using VFD (Variable Frequency Drive) system operated by PLC-SCADA system. The main aim of the paper is to dealt with the concept of speed control of a three-phase induction motor with energy saving. To do so, a VFD (Variable Frequency Drive) is used for controlling the speed of a three-phase induction motor with variable load attached to the motor. It certainly leads to the best performance and high efficiency of the induction motor. Programmable Logic Controller (PLC) and Supervisory Control And Data Acquisition (SCADA) are two new systems to control a Variable Frequency Drive (VFD) whose output is given to a three-phase induction motor and driving a conveyor belt. The conveyor belt has three sensors are inputs which senses a passing object and carries out the necessary instructions programmed in ladder logic programming of the PLC through the computer (PC). The SCADA software installed in the PC in turn enables the human operator to control the entire operation away from the plant and just by using the virtual inputs designated on his computer screen.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Speed Control Schemes Employed in
VFD
• There are mainly two type of control schemes
employed
1. V/F control
In this output AC maintain a ration between Voltage and
Current.
V/f or V/Hz is the basic control scheme employed in AC drives
and is used for Pump applications mainly
In V/f control, current is controlled only based on fault or
over current level.
5. prashob7@outlook.com
Vector Control
• Two closed loop controls :-
Current loop and Speed loop
• Using Mathematical vectors drive can separate
toque producing current from magnetizing
current
• Vector control can tune themselves to the motor
after getting basic motor name plate parameter
• Tuning also known in certain cases as
optimization or auto tuning
6. prashob7@outlook.com
Auto tuning
• Auto tune feature measure several variable of
motor like resistance , inductance of rotor and
stator, slip
• Based on these values mathematical motor
model is setup and thus controls loops are
executed at their best
• New age drives have adaptive tuning feature
which is active continuously as the motor runs
7. prashob7@outlook.com
What are the additional configurations in Vector
drive compared to that of normal V/f drives?
• A feedback circuit with at least two current feedbacks from
the motor leads
• With above configuration vector drives are capable of
“encoder less operation”, however there is provision to
provide encoder/resolver feedback
• More powerful controller to perform vector analysis on
current and voltage feedback
8. prashob7@outlook.com
Advantages of Vector Control
• Vector control can deliver 100% torque form 0 to rated
speed
• Speed control is more precise than that of V/F
• Since closed loop control is excellent, vector control can
be implemented were PID loops or set point is
continuously coming from a process feed back or other
systems
• This control is suitable for applications involving
1. Torque control
2. Basic position control[advance control require servo drives]
3. Electronic gearing , pulse following
4. Tension control with dance adjustment etc
