Event-triggered control of switched linear systems

This paper presents an event-triggered sampling mechanism and develops a sampled-data-based stabilizer for switched linear systems. First of all, state estimators are designed for individual subsystems of the switched system. Secondly, sampling is triggered only if the error between estimated state and sampled state violates a dynamic threshold, and a sampled-data-based controller is designed for the overall switched system to achieve stabilization provided that average dwell time conditions of the switched system are satisfied. Lastly, a numerical example is given to illustrate the effectiveness of the proposed method.
