Nonfragile fuzzy tracking control for nonlinear systems with input and output dynamic quantization

This paper investigates the nonfragile H-infinity output feedback tracking control problem for a class of nonlinear systems with input and output dynamic quantization based on T-S fuzzy model approach. The measurement output and the control input signals will be quantized by dynamic quantizers before them being transmitted to the controller and the actuator, respectively. The attention of this paper is focused on the design of the observer-based nonfragile H-infinity output feedback tracking controller to asymptotically stabilize the nonlinear system and achieve the prescribed H-infinity tracking performance according to linear matrix inequality (LMI) technology. Simulation results are provided to show the effectiveness of the developed design method.
