Optimal PID controller parameters for vector control of induction motors.

In this paper, we proposed methods of computing Proportional, Integral and Derivative (PID) parameters controller for vector control of induction motor. The optimal parameters for current loop, flux loop, and speed loop as function of required settling time and motor parameters will be computed by the proposed method. The significant of the proposed method is that one factor (settling time) is the only parameter required to be given by the user such that the method calculated the PID parameter for each loop control. Simulation results show robustness of the proposed method to system parameters variations.
