基于Smith预估补偿的地下水位模型参考自适应控制器的设计

A Design of the Underground Water Level Model Reference Adaptive Controller Based on the Smith Predictor

针对地下水位控制的纯滞后性和特殊性,本文给出了一种将模型参考自适应控制与Smith-Fuzzy控制器相结合的控制策略,通过对模糊PID参数和Smith预估器滤波时间常数的在线整定与仿真,获得了比普通模糊PID控制和Smith预估器控制更好的控制效果与性能。

According to the pure delay and particularity of the underground water level control, this paper gives a control strategy which combines the model reference adaptive control and the Smith-Fuzzy controller together. Through the online tuning and simulation of fuzzy PID parameters and the Smith predictor filter time constant, this control strategy gets better control effect and performance than the ordinary fuzzy PID control and the Smith predictor control.
