چکیده :

This paper examines robust stabilization for a certain type of nonlinear singular systems in strict feedback form. Different from traditional control strategies that require continuous feedback information, a new event-triggered control (ETC) method is designed to decrease transmission rates of the control action. By decomposing a singular system into a differential component and an algebraic component, a recursive back-stepping control scheme is designed. However, to counteract the effect of sampling errors introduced in event-based control systems, the Input-to State Stability (ISS) small-gain technique is introduced. Moreover, a sufficient condition is derived to guarantee the Input-to-State Practical Stability (ISpS) of the closed-loop system as a whole. Additionally, we rigorously prove that the event-triggered scheme strictly avoids Zeno behaviors. Lastly, a simulation result is provided to verify the efficacy of the introduced scheme.
