Fuzzy PID supervisor
H.R. van Nauta Lemke, Wang De-zhao · 1985
A fuzzy supervisor for a conventional PID controller is described. In the design of the supervisor the knowledge of an expert in tuning the parameters of the PID controller is applied. Moreover, a performance index is formulated, which matches the requirements in real applications better than the integral criteria generally used. In a simulation set-up system performances of the PID controller with and without the fuzzy supervisor are compared for different values of the parameters of the process to be controlled.
