摘要
针对时不变或含跳变参数的时变被控对象建立多个模型 ,并构成多模型输入受限控制器 .每个采样时刻基于性能指标 ,选择与被控对象最接近的模型 ,将基于此模型的控制器切换为当前控制器 .多模型控制器可对时不变被控对象或含跳变参数的时变被控对象 ,在保证输入输出稳定的同时迅速改善瞬态响应 ,并且使输出渐近跟踪设定值 .
In this paper multiple models are used to cover the parameter uncertainty of a time invariant system or a time variant system with jumping parameters, and multi-model input constrained controller is set up based on the multiple models. At every sample time, the closest model of the system is selected by a switching index function, and the controller based on this model can improve the transient response greatly, at the same time the stability of closed-loop system is guaranteed, the output of the closed-loop system tracks the set-point asymptotically.
