### Abstract

In this paper, a dynamic output feedback control problem is investigated for systems with event-driven control inputs. With both continuous and sampled output measurements in the systems, two types of dynamic output feedback controllers are designed based on a predefined event-driven scheduler for the control signals, respectively. With the proposed event-driven control scheme, the Zeno behavior can be avoided, and the states of closed-loop systems are also guaranteed to be globally uniformly ultimately bounded. Detailed parameters of the event-driven controllers are constructed under the stabilizable conditions of the closed-loop systems. Finally, both the effectiveness and merits of the proposed design techniques are verified by the numerical examples.
