The article proposes a dynamic time-varying event-triggered strategy to achieve semi-global finite-time rendezvous control of saturated spacecraft. The main idea of the designed dynamic event-triggered strategy is to construct the controller that contains the time-varying high-gain and a dynamic event-triggered mechanism simultaneously. Moreover, a positive lower bound of interevent times is obtained by using the properties of the parametric Lyapunov equation, such that the Zeno phenomenon is eliminated. Finally, the designed dynamic time-varying event-triggered strategy is verified by simulation results.
