Feed forward and fuzzy control with rule of self-adjusting factors on hydraulic valve-control system

针对液压阀控系统负载的不确定性和扰动性,建立液压阀控系统的数学模型,设计出前馈和自调整因子模糊控制相结合的控制方法,同时分析模糊控制器的控制机理,给出自调整因子模糊控制器的基本结构,在MATLAB/SIMULINK环境下进行仿真验证。仿真结果表明这种控制方法能有效地提高控制系统的控制性能,自调整因子模糊控制和前馈控制环节的结合在液压阀控伺服系统的控制中具有很好的控制效果。

Based on the uncertainty and disturbance in hydraulic valve‐control system of load , the mathematical model of hydraulic valve‐control system is set up ,the control method of feed forward fuzzy control with rule of self‐adjusting factors is designed ,the control principle of the controller is analyzed , the basic structure of the controller is designed , and the simulation is done on the environment of MATLAB /SIMULINK in order to verify this method . The simulated results indicate that the fuzzy control with rule of self‐adjusting factors combined with control of the feed forward can get better control effect in using hydraulic valve‐control system .
