Quantized H∞ static output feedback control for networked control systems with random communication packet losses

This paper is concerned with the problem of quantized H_∞ control for discrete-time networked control systems (NCSs) with random communication packet losses. By choosing appropriate Lyapunov functional, sufficient conditions for the existence of quantized H_∞ controller is derived, such that the closed-loop discrete-time networked control systems is asymptotically mean-square stable and preserves a guaranteed H_∞ performance. An improved design criterion for quantizer is formulated in the form of sector-bounded, it might be simple in designing quantized H_∞ controller. Finally, numerical examples are given to show the effectiveness of the proposed method.
