Fuzzy Sliding Mode Control under Randomly Occurring Gain Fluctuations: A Component-Based Event-Triggered Approach

This paper considers the sliding mode control(SMC) problem for T-S fuzzy system under the component-based event-triggering mechanism(ETM). Moreover, the uncertainties and gain fluctuations in a randomly occurring way are taken into account, and these phenomena are described via two independent Bernoulli processes. Under the component-based ETM, the measurable output component is judged and transmitted independently to reduce the transmission frequency. Then, by virtue of the SMC approach, a fuzzy resilient output feedback controller is designed, which only depends on the triggered output signals. Meanwhile, sufficient criteria are derived to ensure the reachability of the specified sliding surface and the mean-square asymptotical stability of the closed-loop fuzzy system. Finally, we provide the simulation results for verifying the proposed control strategy.
