This paper is concerned with the problems of H∞ control for networked control systems with communication
constraints. An improved networked control system model is proposed, while the effects of logarithmic quantization, packet
dropout, delay and probabilistic sensor fault are considered simultaneously. Sufficient condition for the stochastic stability of
the closed-loop system is given in terms of linear matrix inequality. A controller is designed such that the closed-loop system
is stochastic stable and achieves the given disturbance attenuation level. Numerical example illustrates the effectiveness of
the proposed method.
