The event triggered control for a kind of switched linear parameter varying (LPV) systems is studied. The authors present two event triggering schemes for such systems, depending on whether the controllers are pre‐designed or to be designed. In the cases of pre‐designed controllers, they present the state and parameters dependent event triggering scheme. In the case of controllers to be designed, two event triggering schemes are given, depending on the state and parameters, respectively. The feasible linear matrix inequality (LMI) conditions are given for designing controllers and event triggering thresholds. The minimum of trigger time intervals is obtained as a positive number. Under the average dwell time switching mechanism, the switched parameter‐varying system is exponentially stable. Finally, the validity of designed approaches is verified through a simulation example for an aircraft engine model.
