This paper is concerned with the quantized H ∞ state feedback control problem for discrete-time systems subject to limited communication capacity, which includes state quantization and random sensor packet losses. By introducing a random packet-loss model, an quantized state feedback 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.
