Event-triggered sliding mode control for networked switched systems with quantization parameter

The purpose of this paper is to propose an event-triggered sliding mode control for quantized switching systems to cope with the stability problem of switching systems under the event-triggered scheme. Firstly, this paper proposes an event-triggered mechanism based on quantization parameters, in which the dynamic quantization mechanism ensures that the system state stays within the quantization range, while the event triggering ensures the communication security, reduces the interference signals, and improves the resource utilization. Secondly, combined with the event-triggered control strategy, the sliding mode dynamics is deduced with the help of the construction of the sliding surface function, and the stabilization criterion with the perturbation attenuation performance of H

significance is established through the inequality technique, and on the basis of which a new type of control scheme is adopted to ensure the accessibility of the sliding surface. The Zeno behavior is eliminated by calculating the lower limit of the event triggering interval. Finally, the results are validated by simulations.
