Design and analysis of a new pid fuzzy controller
Chin‐Wang Tao, J.S. Taur · Journal of the Chinese Institute of Engineers · 1996
In this paper, a methodology is proposed to design a robust fuzzy controller for a positional control system. This fuzzy controller is based on the Proportional‐Integral‐Derivative control scheme with fuzzy if‐then rules and the triangular membership functions. The design of the new structure of this PID fuzzy controller is presented. Also the characteristics of the PID fuzzy controllers are analyzed. The simulation results for positional control systems with a second or a third order plant are included to show that the PID fuzzy controllers out‐perform the traditional PID controllers in the sense of robustness. Moreover, simulation results of a fourth order plant are provided to empirically illustrate the effectiveness of the design approaches for higher order systems.
