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