This paper contributes to the derivative-based event-triggered controller design of switched nonlinear cyber-physical systems (CPSs) subject to actuator saturation. Based on the state of the system and its derivative, a novel derivative-based event-triggered mechanism (DETM) is presented. A proposition is derived to show that the proposed DETM could generate a larger inter-event time than the existing normal ETM. By taking the average dwell time method, sufficient conditions for the existence of an event-triggered controller are established, which guarantee the exponential stability of switched nonlinear systems with actuator saturation. Finally, the advantage of the presented approach is illustrated by some simulation results.
