Optimization techniques are become more popular
for the improvement in control of Three Phase Induction Motor
(TIM). Also the Volt/Hz (V/f) control and space vector pulse
width modulation (SVPWM) are used to reduce the harmonics
level related to other control and modulation techniques. This
paper deals with the tuning of PI controller parameters to be
used in TIM. Particle Swarm Optimization (PSO) algorithm is
used to tune each parameter of PI speed controller to improve
the speed response performance of the TIM. By designing
appropriate PSO algorithm, Kp and Ki of the PI speed controller
parameters are tuned for TIM operation with SVPWM
Switching and V/f Control. The performance of PI speed
controller on the TIM is measured by estimating the change of
speed and torque under speed response condition. It is found that
the performance of the PI controller is robust in terms of
overshoot, settling time, steady state error and RMSE.
