Application of Fuzzy-PID Controller in Hydraulic Load Simulator

In modern industries, hydraulic actuator systems take an important part in recent years due to their advantages including high durability and the ability to produce large forces at high speeds. Therefore, hydraulic actuator has a wide range of application fields where controlled force or pressure with high accuracy and fast response is the most significant demand. Consequently, many hybrid actuator models have been developed to research about control force or pressure with best results. This paper presents a new kind of hydraulic load simulator using a fuzzy-PID controller for force control. Experiments are carried out to evaluate the effectiveness of the proposed control method applied for hydraulic systems with varied external disturbance as in real working conditions.
