Observer-Based Sliding Mode Control for Fuzzy Systems Under Stochastic Communication Protocol

This brief seeks to introduce an observed-based sliding mode control (SMC) for fuzzy systems with stochastic communication protocol characterized by a more general switching rule. In contrast to prior research, the innovative stochastic switching rule for the stochastic communication protocol is unique in that it incorporates both sojourn probability and sojourn time concurrently, aiming to enhance communication efficiency and mitigate computational complexity. Additionally, by capitalizing on observed state information, a fuzzy sliding surface is devised, and a suitable fuzzy SMC law is suggested to ensure the reachability of the designated sliding function. Ultimately, the efficacy of this proposed control strategy is confirmed through a tunnel diode circuit model.
