This paper investigates dynamic event-triggered control for systems subject to asymmetric actuator saturation. The asymmetric saturation could severely degrade the performance of systems, which always exists in control engineering. A dynamic event-triggered scheme considering the character of asymmetric saturation is proposed to reduce triggered number of events, under the premise that the closed-loop system subject to asymmetric actuator saturation is asymptotically stabilized. Sufficient conditions are derived to stabilize the system and the minimum inter-event time interval is calculated to exclude Zeno behaviour. An optimization problem is solved to estimate the contractive invariant set as the stable region of the system. A numerical example is given to illustrate the theoretical results.

This paper investigates the problem of event-triggered control for systems with asymmetric input constraint by establishing a novel saturation-related triggering condition, which could reduce the number of events. By designing a subregion-based control law, a sufficient condition is deduced to ensure the asymptotic stability of the underlying system with the proposed triggering rule.Moreover, an optimal algorithm is formulated to estimate the domain of attraction of the closed-loop system. Finally, a numerical example is provided to demonstrate the effectiveness of the derived approaches.
