Networked predictive output feedback control of networked control systems

This paper is concerned with the design of packet-based output feedback controller for networked control systems (NCSs) with random network delay and data dropout. By taking the full advantage of the packet-based transmission in NCSs, a packet-based control approach is proposed to actively compensate the delay and data dropout under Markovian jump linear system framework. Different from previously reported packet-based control approaches to NCSs, an output feedback strategy is used to generate the control input packet. A new necessary and sufficient condition is proposed to perform the stability analysis of networked closed-loop system. Furthermore, by using the recently established singular Markovian jump system theory, the controller design problem is solved. Finally, the effectiveness of the proposed method is illustrated by using a numerical example.
