Output feedback delay compensation control for networked control systems with random delays

This paper is concerned with the design and analysis problems of output feedback delay compensation controller for networked control systems (NCSs) with random network delay. By taking the full advantage of the packet-based transmission in NCSs, a delay compensation control approach is proposed to actively compensate the network-induced delay in Markovian jump linear system framework. Different from previously reported delay compensation 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. (C) 2013 Elsevier Inc. All rights reserved.
