【Abstract】 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.更多还原
