【摘要】 提出一种电液比例阀的模糊与自适应模糊PID复合控制设计及MATLAB仿真。在大偏差情况下采用模糊控制,小偏差时采用自适应模糊PID控制,仿真结果表明该方法具有模糊控制的PID动态响应快、超调量小和抗干扰能力强等优点,是一种更加有效的控制策略。更多还原

【Abstract】 A kind of fuzzy and adaptive fuzzy-PID control of electro-hydraulic proportional pressure valve and its MATLAB simulation have been put forward.Using fuzzy control in the case of large deviations and self-adaptive fuzzy-PID in the case of small.Comparing with traditional PID controller,the fuzzy and self-adaptive fuzzy-PID controller has faster response,lower overshoot and better anti-interference capability,which is a more effective strategy.更多还原
