On designing network-based H∞ controllers for stochastic systems

This paper is concerned with network-based H∞ stabilization for stochastic systems, where network-induced delays, packet dropouts, and packet disorders are taken into account simultaneously. The packet disorders arising from both the sampler-to-controller channel and the controller-to-actuator channel are considered by introducing a logic controller and a logic zero-order hold. The network-induced delays and packet dropouts are modeled as a constant delay plus a non-differentiable time-varying delay in the input.
