Abstract

A new tuning method is proposed for fuzzy PID controller based on internal model control theory. First, the analytical model of the fuzzy PID controller is expressed as a linear PID controller plus a nonlinear compensation item. Then, the internal model control method can be used to approximately design the parameters of fuzzy PID controller analytically. Finally, stability of the fuzzy PID control system is analyzed, and the validity of the tuning methodology is demonstrated by simulation.
