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

This paper investigates the nonfragile ℋ
∞
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
