Abstract

This article presents particle swarm optimization -based optimal gain tuning of proportional integral speed controller in an induction motor drive with mine hoist load diagram. Optimization considers the load and speed variations, and provides appropriate gains to the speed controller to obtain good dynamic performance of the motor. IM performance is checked with the optimal gains through the simulation studies in MATLAB/SIMULINK environment. Results are compared with hand tuning and fuzzy logic speed controller. Hybrid of FL and PSO-based PI controller for the speed control of given motor is also performed to eliminate the drawbacks of PI controller and FL controller . From the simulation studies, hybrid controller produces better performance in terms of rise time, overshoot and settling time
