Event-Triggered Dynamic Output Feedback Control for Switched Singular Systems With Asynchronous Switching

This manuscript investigates the output-based event-triggered control problem for switched singular systems via the dynamic output feedback controller. To enhance communication efficiency and reduce transmission load, a discrete-time event-triggered scheme based on the output is proposed. Considering the asynchronous switching between the system and the controller due to the event-triggered conditions, the closed-loop system (CLS) is formulated by incorporating an augmented switching signal through the signal merging method. By utilizing the mode-dependent Lyapunov function method and the average dwell time (ADT) technique, sufficient criteria are established to ensure the CLS be regular, impulse-free and E-uniformly ultimately bounded (E-UUB). Additionally, by employing an improved matrix decoupling approach, solvable linear matrix inequality (LMI) conditions are derived, and the co-design strategies for controller gains and event-triggered scheme parameters are presented. Finally, two examples are provided to demonstrate the advantages of the proposed approaches.
