A new approach to network-based H-infinity control for stochastic systems

In this paper, the problem of network-based control for a class of stochastic systems has been addressed. The network-based control system with induced delays and packet dropouts has been modeled as a time-delay stochastic system with two successive delay components in the state. The H∞ controller design method has been further extended to a more general case, where the system matrices of the physical plant contain parameter uncertainties. Delay fraction method has been used to reduce the conservatism. Three numerical examples have been given to illustrate the usefulness and effectiveness of the proposed method
