Discrete-Time MIMO Reset Controller and Its Application to Networked Control Systems

摘要

Reset control has been shown to have advantages over linear time-invariant controllers, especially, for control loops with time-delays. In this paper, in order to adapt reset control to networked control systems (NCS), multi-input multi-output discrete-time reset control model is first established by decomposing the controller output and defining appropriate flow set and jump sets. Then, we apply discrete-time reset controllers to NCS with time-varying delays in both forward and feedback channels, the modeling framework of networked reset control systems is given based on switched linear parameter-varying systems, and stability conditions are derived in terms of linear matrix inequalities. Finally, experimental and simulation examples are presented to illustrate the superior performance of the proposed approaches.
