Abstract
This brief endeavors to exploit the sliding mode control problem for fuzzy singular perturbed systems in the presence of dynamic quantization and dynamic event-triggered protocol. With respect to the characteristics of the dynamic quantizer, a novel dynamic event-triggering protocol associated with the singular perturbation and the dynamic quantization parameters is proposed to further decrease the communication load. A co-design scheme is addressed for determining the triggering and the quantization parameters. Additionally, a fuzzy sliding mode controller is designed with respect to the singular perturbation parameter, and the mode-based controller is designed for ensuring the finite-time boundedness of the closed-loop systems and the reachability of the specified sliding surface. Eventually, two simulation results are conducted to verify the rationality of the attained scheme.
