Abstract :
This paper is concerned with the guaranteed cost controller design of networked control systems. The continuous time plant with state-delay is studied. A new model of the networked control systems is proposed under consideration of the network-induced delay and data packet dropout. In terms of the given model, a suboptimal guaranteed cost controller design method is proposed based on linear matrix inequalities (LMI) approach. Suboptimal allowable equivalent delay bound (SAEDB) and the feedback gain of a memoryless controller can be derived by solving a set of LMI for the networked control system based on Lyapunov functional method. An example is given to show the effectiveness of our method
