Hydraulic Cylinder Servo Position Control Using a Fuzzy Controller

Based on the fuzzy sets theory, a fuzzy controller that can undertake real-time fuzzy inference and fuzzy operation is designed to accomplish hydraulic servo position control through a PC9821 personal computer. After simulation and experiment, the dynamic characteristics of the fuzzy controller is compared with those of the conventional PID controller, with the conclusion that the fuzzy controller has many advantages in its applications on hydraulic control systems.
