Comparative Analysis of Pso-Pid and Hu-PidIJERA Editor
PID control is an important ingredient of a distributed control system. The controllers are also embedded in many special purpose control systems. PID control is often combined with logic, sequential functions, selectors, and simple function blocks to build the complicated automation systems used for energy production, transportation, and manufacturing. Many sophisticated control strategies, such as model predictive control, are also organized hierarchically. PID control is used at the lowest level; the multivariable controller gives the set points to the controllers at the lower level. The PID controller can thus be said to be the “bread and butter‟ of power system engineering. It is an important component in every control engineer‟s tool box. PID controllers have survived many changes in technology, from mechanics and pneumatics to microprocessors via electronic tubes, transistors, integrated circuits. The microprocessor has had a dramatic influence on the PID controller
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
HEAP SORT ILLUSTRATED WITH HEAPIFY, BUILD HEAP FOR DYNAMIC ARRAYS.
Heap sort is a comparison-based sorting technique based on Binary Heap data structure. It is similar to the selection sort where we first find the minimum element and place the minimum element at the beginning. Repeat the same process for the remaining elements.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

2. Controllers :
A controllers is a control system that manages, commands, directs, or regulates the
behavior of other devices or systems using control loops. It can range from a single
home heating controller using a thermostat controlling a domestic boiler to large
Industrial control systems which are used for controlling processes or machines.
Type of Controllers :
1. Proportional Controller (P)
2. Proportional Derivative Controller (PD)
3. Proportional Integral Controller (PI)
4. Proportional Integral Derivative Controller (PID)
2
3. Proportional Integral (PI) Controller:
A proportional integral controller is a feedback control loop that calculates an error
signal by taking the difference between the output of a system.
As the name suggests in integral controllers the output (also called the actuating
signal) is directly proportional to the integral of the error signal.
Integral Controllers used alongside with proportional controllers are called PI
controllers.
PI controller equation:
Just like PD controller it also has a parallel connection of P and I controllers.
3
4. Proportional Derivative (PD) Controller:
This kind of action gives an output which is proportional to the derivative or the rate of
change of the error.
Derivative control is not used separately (without proportional (P) and integral (I) control) in
a closed-loop system because if the error is constant and non-zero, then the output of
the derivative controller is zero. So it won't work.
Derivative control is usually found in combination with proportional control,
to form so called P+D.
4
5. Proportional-Integral-Derivative (PID) Controller:
PID controller involves all the three controllers P, PD and PI connected in parallel.
The PID instruction is an output instruction that controls physical properties such as
temperature, pressure, liquid level or flow rate using process loops.
PID controller involves the parallel combination of these 3 controllers and the output
equation is proportional to the derivative as well as integral of the error signal.
5
6. The Characteristics of P, I, and D controllers
A proportional controller (Kp) will have the effect of reducing the rise time and will
reduce, but never eliminate, the steady-state error.
An integral control (Ki) will have the effect of eliminating the steady-state error, but it may
make the transient response worse.
A derivative control (Kd) will have the effect of increasing the stability of the system,
reducing the overshoot, and improving the transient response.
All design specifications can be reached with the PID controller and 100%
desired conditions can be achieved .
