Observer-based Event-triggered Sliding Mode Control for Switched Systems

This paper considers the problem of the observer-based event-triggered sliding mode control for switched systems Firstly, due to the unavailable state of the system, an event-triggering communication scheme based on the system output is proposed to save communication resources. Secondly, a common sliding surface is designed and the stability conditions of the sliding mode dynamics is presented in terms of linear matrix inequalities. An adaptive event-triggered sliding mode controller can ensure the retainability of the sliding surface. Thirdly, the positive lower-bound of the inter-execution time intervals is provided such that the Zeno behavior can be excluded. Finally, the effectiveness of the proposed method is demonstrated by a simulation.
