Abstract :
In this paper the relative difference between stabilizing curve for Proportional Integral Derivative controller and Generalized Proportional Integral controller on transient and dynamic performances are discussed. It is observed that the Generalized Proportional Integral controller provides a good stabilization than the Proportional Integral Derivative controller in terms of delay time, rise time, peak time, settling time, and maximum peak over shoot and steady state error. This shows a greater degree of robustness in terms of disturbance rejection represented by severe changes in static and dynamic loads.
