| Abstract |
This paper discuses the simulation results of an input-output feedback
linearizing (FBL) and proportional-integral (PI) controllers as applied to drive a dc shunt motor for speed control application. A comparison study of the performance of both the controllers are carried out. It is concluded from the simulation results that feedback linearizing controller provides improved response as compared to PI controller in reducing oscillations, overshoot and settling time during a step change in reference speed or load torque. Moreover, the FBL controller also shows robustness to motor parameter variations. |
