Abstract— In this paper, the problem of event-triggered sliding mode control for linear singular systems is studied. The aim is to design a sliding mode control law under an event-triggered sampling scheme such that the uncertain singular system is admissible. First, a new Zeno-free event-triggered condition is proposed to detect the sampling time instants. Then an integral sliding surface is introduced, and sufficient conditions to satisfy the admissibility of the sliding dynamic. The design parameters related to the event-triggered sampling scheme and sliding surface are obtained by solving some linear matrix inequalities solvable by MATLAB software. The event-triggered sliding mode controller is designed to drive the trajectories of the system to the sliding surface in a finite time. Finally, the results of the simulation on an illustrative example show the validation and efficiency of the proposed controller
