Abstract: This paper considers the dynamic output-based event-triggered strategy design for linear systems subject to input saturation. The dynamic event-triggered control reduces the communication burden, and a minimum inter-event time is explicitly provided to exclude Zeno behaviour. A dynamic linear anti-windup augmentation is presented to deal with the input saturation. For the given anti-windup compensator, a criterion is formulated to achieve practical stability with finite $\mathcal {L}_2 $L2 gain. Moreover, an algorithm with projection lemma is proposed to design the anti-windup augmentation when it is unknown. For two special cases, i.e. the anti-windup compensator is static or of the plant-order, the feasibility conditions become convex. Simulations are given to illustrate the theoretical results.
