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。
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 inferences is proposed in this paper ,using fuzzy inferences method , the PID parameters can be adjusted adaptively on line for varying state of the system. This approach has more performance and robustness than conventional PID controllers in any conditions, it can be validated by the simulation.
