摘要：

This paper discusses an effective anti-disturbance control algorithm for the typical networked control systems (NCSs) under the event-triggered frame. Firstly, a disturbance observer (DO) is designed to dynamical estimate unknown exogenous disturbances. Secondly, in order to reduce the usage of channels, the event-triggered instead of the periodic sampling mechanism is used. By combining the networked state feedback control with the estimation value of disturbances, an event-triggered composite controller can be proposed based on the designed trigger condition. An LMI-based algorithm is given to compute the controller gain and the observer gain, where the stability of the closed-loop NCSs can further be proved. Finally, the dynamical simulation results of A4D models can show the feasibility of the proposed algorithm.
