【摘要】 链梯速度具有随负载而变化的时变特性,当负载变化时,采用传统的PID控制很难满足要求,为此本文提出了一种基于模糊推理的PID控制器,它利用FUZZY推理,对系统所处的不同状态实现PID参数的在线自适应控制,使系统在任何状态下,都能得到比传统的PID更好的控制效果和更强的鲁棒性,仿真结果也证明了这一点。更多还原

【Abstract】 The speed of chain - ladder has the characteristic of time- varying and it changes following the change of load. The conventional method can ’ t meet the requirement when the loads vary .therefore, a new PID controller based fuzzy infer- ences is proposed in this paper ,using fuzzy inferences method , the PID parameters can be adjusted adaptively on line for vary- ing state of the system. This approach has more performance and robustness than conventional PID controllers in any condi- tions, it can be validated by the simulation.更多还原
