Sliding mode control for Markovian jump systems under a switched scheduling protocol

This article is concerned with the sliding mode control for Markovian jump systems under transmission constraints. To deal with node congestions, a switched channel scheduling scheme integrating round-robin (RR) protocol and weight try-once-discard (WTOD) protocol is proposed to orchestrate the priority of multiple sensor nodes. At each transmission instant, a system performance-based detector is adopted to select one scheduling protocol between RR and WTOD in a certain event-triggering manner, by which only one sensor node has the priority to access the network. Compared with conventional protocols, the proposed scheduling scheme establishes a dynamic coupling mechanism between channel resource and scheduling rules, aiming to strike a balance between improving system performance and reducing communication resource requirements. Then, a token-dependent sliding mode controller is constructed, and a genetic algorithm-based optimization problem is given to achieve smaller convergent domain. Finally, numerical examples are shown to verify the present control strategy.
