摘      要：Model-based control strategy is introduced for improving the closed-loop performance of switched systems under network communication in this paper. In traditional networked control system, a ZeroOrder Hold (ZOH) is often used at the controller side to realize continuous feedback control. However, to use a ZOH usually decreases control accuracy since the state will be held invariably during each sampling period. In order to improve control accuracy, we introduce a model-based control strategy instead of ZOH-based one and propose two analysis frameworks for switched linear systems in network communication environment with periodic sampling mechanism (PSM) and event-triggered sampling mechanism (ETSM), respectively. A model-based dynamic switching controller is set up with certain robust performance. Asynchronous switching is taken into account since the switching time sequence of the controller is determined by the network transmission time sequence which cannot coincide with the controlled system. Under switching and control gain conditions, stability criteria of the closedloop switched system in network communication environment are derived and verified through two simulation examples.
