Adaptive event-triggered non-fragile sliding mode control for uncertain T-S fuzzy singular systems with passive constraint

This paper discusses the non -fragile SMC problem of uncertain discrete -time TSFSSs with passive constraint based on the event -triggered method. A novel AETS is adopted to save communication resources while maintaining good control performance. According to Lyapunov function method, sufficient admissible conditions of the sliding mode dynamics are established to ensure passive performance. Throughout the entire design process, the difference singular matrix of the system under consideration is fully taken into account to make it easy to check the given conditions. Under the fuzzy environment, the non -fragile SMC law under the AETS is determined to ensure the reachability condition. Finally, two examples are provided to verify the effectiveness of the given control strategy.
