This paper presents simulation results for three phase, 6/4 poles switched reluctance
motor (SRM) by using particle swarm optimization (PSO) method for formative the
optimal proportional-integral-derivative (PID) controller tuning parameters.The
proposed approach has superior feature, including easy implementation, stable
convergence characteristics and very good computational performances efficiency.
The main focus of this paper is to investigate the dynamic performance of switched
reluctance (SR) motors. This investigation is achieved through simulation using
MATLAB/SIMULINK. Digital simulation results show that the designed (PSO) have
a good dynamic behaviour of the motor, a perfect speed tracking with no overshoot
and a good rejection of impact loads disturbance. The results of applying the (PSO)
mode controller to a SRM give best performances and high robustness than those
obtained by the application of others controller. The obtained results of the closed loop
PSO-PID response shows excellent performance with respect to the PID controller.

Pulse Width Modulation for DC Motor Control Based on LM324

The DC motor is an important part of an equipment in many industrial applications requiring variable speed and load characteristics due to its ease of controllability.
Nowadays, there are lots of good-quality motor speed controllers on the market. However, their costs are relatively high. A speed controller with both low cost and good performance will be highly marketable, especially for small mobility applications.
The current work allows controlling the speed of a DC motor in both forward and reversing direction, from fully off to fully on. It runs in switch mode so it is quite efficient. In this work, designing motor bi-directional DC control circuit using Pulse Width Modulation (PWM) based on an operational amplifier model LM324 is implemented.
The proposed system offers many advantages such as simple structure, low cost, accurate, quite efficient, lightweight nature, small volume, and bi-directional speed control.

In this paper, the output frequency of a self excited induction generator (SEIG)
driven by wind turbine and supplies static load are controlled. The principle connections
of wind energy conversion are presented. The dynamic modeling of the wind turbine
and its linearization are derived. The PID controller which employed for turbine rotor
speed control and hence the frequency regulation is proposed. The block diagram of the
proposed speed control system which consists of speed controller, actuator model and
the turbine linearized model is simulated by Matlab-Simulink software package

This paper describes the design and implementation of a personal computer
based closed loop DC motor speed control system Using LabVIEW 8.5 Package
for data manipulation and interface control. Tuning the parameters of the PID
controller is done using trial and error method by conducting simulation on the
system model using Matlab package. This method is used to find the best system
response depending on the tuning parameters of the PID controller. These
parameters are then implemented in the designed real time digital PID controller
system based on LabVIEW package.
Carrying out the task of tuning the PID controller on the real time model requires
great effort and time consuming especially in the early stages. Thus the PID
controller tuning is firstly carried out on the simulation model in Matlab which is
time saving and gives close parameter approximation for applying in the real time
system directly. The PID control action in the real time system shows more
oscillation in comparison with the PID simulation control action. Simulation and
real time results for the speed control of the DC motor experiment were found to
have a high degree of agreement in maintaining the desired speed of the motor.
