This article investigates the problem of event- triggered anti-disturbance (ETAD) in cyber-physical systems (CPSs) under multiple disturbances. The objective is to mitigate the effects of multiple disturbances and to conserve signal transmission resources. Firstly, a dynamic event-triggered (ET) mechanism directly associated with the control input signal is introduced. Subsequently, an ETAD controller was designed based on the previously proposed ET mechanism, aiming to eliminate and compensate the adverse effects of multiple disturbance on CPSs. Furthermore, under the established ETAD controller, theoretical conditions are provided to eliminate and compensate for multiple interferences while saving network transmission resources. Finally, the designed ETAD control strategy can be successfully and effectively applied to radar tracking systems within CPSs under the influence of multiple interferences, as confirmed by simulation verification.
