Research on Fuzzy Adaptive Control of Multi-Cylinder Synchronous Hydraulic System

Abstract:

In large continuous rolling process, that the roller can be accurately control have an important impact on production. In allusion to the characteristics of variable and nonlinear of hydraulic servo system parameters for controlling roller position, fuzzy PI control and adjusting the parameters in on-line are used, in order to realize the three cylinder synchronous control. The research results indicate: for system with external force disturbance, the fuzzy adaptive control has a strong anti-interference ability, and improve the robustness of the control system of multi-cylinder synchronization, as a result, to obtain the satisfactory control effect. To be carried out simulation with Matlab, the results show that the fuzzy PI control scheme is a high precision, efficient and feasible method, and can obtain the satisfactory results.
