This investigation proposes an event-triggered-based antidisturbance switching control technique for the switched Takagi-Sugeno (T-S) fuzzy systems (FSs) subject to multiple disturbances as well as unavailable system state. The disturbances are comprised of two parts, i.e., the unavailable modeled disturbances and the available unmodeled disturbances. First, a composite observer is constructed to capture the unavailable system state and unavailable modeled disturbances. Then, on the basis of the observer, a switching controller with an event-triggered program inserted is established. Meanwhile, a switching criterion is formulated. Further, under the developed controller and switching criterion, the sufficient conditions are presented for the switched T-S FSs to achieve the multiple disturbances suppression and the communication transmission resource saving. In the end, the reasonability of the raised event-triggered-based antidisturbance switching control scheme is verified with the employed simulation example.
