Quantized H∞ control for networked control systems with multiple packet dropouts

Abstract

This paper is concerned with the problem of quantized H∞ control for networked control systems (NCSs) with multiple packet dropouts. A new model is given to describe the systems with the input and output quantization and multiple packet dropouts. Both the multiple measurement and control packet dropouts are described by two binary switching sequences that obey certain conditional probability distribution. An observer-based controller is designed to ensure the exponentially mean-square stable of the closed-loop system and to guarantee an optimal H∞ disturbance attenuation level. Finally, a simulation example is given to demonstrate the effectiveness of the proposed method.
