提出了一种采用前馈控制器补偿负载的扰动并在系统的主控制回路上采用模糊控制和PID控制相结合的精密电液比例调速系统 ,分析了该系统的组成和控制原理 ,介绍了前馈模糊 -PID控制器的设计方法 .理论分析和实验表明 ,该控制策略可以取得较为满意的控制效果 .
A kind of precise electro-hydraulic proportional speed control system which uses the feedforward controller to compensate the disturbance of the load and uses the fuzzy control and the PID control in the main control loop of the system is introduced. The composition and control principle of the system are analyzed. Feedforward fuzzy-PID controller design method.The theoretical analysis and experiments show that the control strategy can achieve a more satisfactory control effect.
