In this paper, we consider design of H_∞ feedback control systems with quantized signals. We first assume that a state feedback has been designed for a continuous-time LTI system so that the closed-loop system is (Hurwitz) stable and a desired H_∞ disturbance attenuation level is achieved, and that the states are quantized before they are passed to the controller. Since the quantization error may deteriorate the system's performance, we propose a state-dependent strategy for updating the quantizer's parameter, so that the system is asymptotically stable and achieves the same H_∞ disturbance attenuation level. We then extend the result to the case of observer-based dynamic output feedback where the measurement outputs are quantized, and propose an output-dependent strategy for updating the quantizer's parameter.
