    Abstract: Recently, Particle Swarm Optimization (PSO) technique has been utilized in different electrical drives
for velocity control. This study proposes this technique for online tuning PID controller parameters used to
drive the Linear Induction Motor (LIM). A three phase inverter based on Sinusoidal Pulse Width Modulation
(SPWM) technique is employed to obtain the required output voltage supplied to the main windings of the LIM
to control the velocity with minimum harmonics and good characteristics. The end effect is taken into account
in dq axis equivalent circuit. The simulation results proved that the proposed controller is more effective to
improve the performance of the motor.
