Speed performance enhancement and analysis of a three-phase induction motor driving a pump load using vector control technique

Abstract

Speed control of an induction motor driving a pump load using vector control technique with proportional integral derivative controller, fuzzy logic controller and hybrid of proportional integral derivative fuzzy logic controllers is presented in this paper. The induction motor drive was designed and simulated with these controllers using MATLAB/Simulink software package. The performance of the induction motor using proportional integral derivative(PID) controller, fuzzy logic controller (FLC) and hybrid controller (FLC-PID) on this load was studied and compared .steady state error of PID, FLC, and FLCPID are 0.5rad/sec, 0.5rad/sec, and 0,1rad/sec respectively, while the undershoot are also respectively 20%, 6% and 4%.FLC-PID further gives arise and settling time of 0.1sec and 0.05sec respectively. From the results obtained, the hybrid controller provides a far more superior performance in enhancing the speed performance of the induction motor.
