Abstract: In quantized feedback control systems, the mismatch of quantizer sensitivity parameter can reduce the system performance; it can even result in the instability of the system. On the other hand, this mismatch will increase the control design complexity and difficulty. This paper is concerned with the supervisory-based sliding mode quantized feedback stabilization problem for a class of uncertain systems in the presence of mismatch between quantization sensitivity parameters. By the utilization of the supervisory control strategy, the proposed robust quantized feedback sliding mode control law can eliminate the effect of mismatch of sensitivity parameters and model uncertainties, and drive the state trajectories to the origin asymptotically. An example is shown to verify the validity and advantage of the theoretical results through Matlab simulation.
