Adaptive Dynamic Event-Triggered Sliding Mode Tracking Control of Pneumatic Vibration Isolation System

In this paper, an adaptive dynamic event-triggered sliding mode control scheme is proposed for a pneumatic vibration isolation platform. First, an experimental platform is designed and constructed, and a corresponding dynamic model is established, which explicitly accounts for the unknown threshold voltage at the input side. Based on this model, an adaptive sliding mode controller is developed. Then, to suppress unnecessary actuator updates, a dynamic event-triggered mechanism is introduced. Lyapunov-based analysis demonstrates the stability of the closed-loop system and guarantees the exclusion of Zeno behavior. Finally, experimental results on the pneumatic platform verify the effectiveness and superiority of the proposed approach.
