In this Paper, a continuous type fuzzy controller(FC) is designed for thePWM electrohydraulic position control system which is mainly composed of four highspeed switching valves. A real-time control system is constructed. Thereafter, the scal-ing factor of FC is adjusted on-line by means of heuristic search algorithm. Experimentsshow the validity of the fuzzy controller in PWM electrohydraulic position control sys-tem.
