Joint Design for Hybrid Bumps Suppression and Disturbance Attenuation of Switched Fuzzy Systems Under Bump-Dependent Dynamic Event-Triggering
Siyuan Zhang, Jun Yan Zhao · IEEE Transactions on Automation Science and Engineering · 2025
In this paper, the anti-disturbance bumpless transfer control problem is addressed for switched fuzzy systems without stable subsystems under event-triggering. First, we establish an original characterization of the anti-disturbance hybrid bumpless transfer performance to simultaneously attenuate disturbances and abrupt large hybrid bumps caused by both switching and triggering. Second, a novel dynamic event-triggered scheme that incorporates triggering-induced bumps and switched turning parameters is designed to improve bumpless transfer performance further. Then, solvability conditions are developed for the considered anti-disturbance hybrid bumpless transfer control problem. Moreover, the bump-dependent dynamic event-triggered scheme, a state-dependent switching law, and disturbance-observer-based event-triggered controllers are designed simultaneously. Finally, a tunnel diode circuit model and a numerical example are used to verify the effectiveness of our method.
