Study of fuzzy learning control for electro-hydraulic servo control systems

In this paper, the approach to combining the iterative learning control with the fuzzy control method is presented. The system not only has advantage of strong robustness in fuzzy control, but also uses appropriate learning arithmetic to update defective fuzzy rules. The reasonable fuzzy learning controller is designed and applied to an electro-hydraulic servo force control system. The result of simulation shows that the fuzzy learning control is superior to the conventional PID control systems.
