PID control scheme has been widely used in most process control system. Because the PID controller has a simple structuer, and have three parameters at the most. However, since it is difficult to determine suitable parameters, a lot of researches have been reported with respect to tuning scheme of PID parameters. In this paper, a design scheme of PID control system using a GMDH (Group Method of Data Handling) network and a genetic algorithm (GA) is proposed. Furthermore, the effectivness of the newly proposed scheme is evaluated on a simulation example.
