COMPARISON PERFORMANCE OF DIFFERENT PID CONTROLLERS FOR DC MOTOR

Abstract

Speed control of Dc motors is an important issue also shorter settling time is desired . In this work at first a parallel PID compensator which adjusted by Ziegler – Nichols is designed but Ziegler – Nichols don't apply directly for all structures of PID controller ,drive equations to applied Ziegler - Nichols for this configuration of PID compensator . The controller design process requirements are discussed by programming . Then the comparison between the PID configurations shows that the PID controller significantly reduced the overshoot , settling time and has the best performance encountering with system uncertainties . According to the matlab programming version 7.10 results , the D*PI controller has better performance than the PID configuration
