Abstract

In order to improve control performance in both dynamic transient and steady-state periods, this paper presents an enhanced hybrid FUZZY P+ID controller that is constructed by using an incremental fuzzy logic controller with twenty-five rules in place of the proportional term in a conventional PID controller. The enhanced FUZZY P+ID controller has only two additional parameters to be tuned based on its PID counterpart. The analysis shows that the stability behavior of a control system remains unchanged after replacing the PID controller by the FUZZY P+ID controller. Numerical simulation results of a nonlinear system for both step and tracking control demonstrate the superior control performance of the FUZZY P+ID controller
