Robust H∞ control and filtering of networked control systems

This paper is concerned with the design of robust H∞ controllers and H∞ filters for uncertain networked control systems (NCSs) with the effects of both the network-induced delay and data dropout taken into consideration. A new analysis method for H∞ performance of NCSs is provided by introducing some slack matrix variables and employing the information of the lower bound of the network-induced delay. The derived criteria for the design of H∞ controller and H∞ filter are expressed as a set of linear matrix inequalities. Numerical examples and simulation results are given finally to illustrate the effectiveness of the method.
