A static output feedback based event-triggered control mechanism for a class of switched nonlinear systems with a passivity property is proposed in this paper. Each subsystem of such a switched system does not necessarily have passivity in the classical sense, while maintaining the passivity property only on the active time intervals. Moreover, passivity is based on multiple storage functions and the storage functions are allowed to increase at switching instants. The proposed event-triggered output feedback controller can not only maintain asymptotic stability but also exclude Zeno behavior under some conditions. Finally, a numerical example is presented to illustrate the effectiveness of the method.

针对一类具有无源特性的切换非线性系统，提出了一种基于静态输出反馈的事件触发控制机制。这种切换系统的每个子系统不一定具有经典意义上的被动性，而仅在活动时间间隔上保持被动性。此外，无源性基于多种存储功能，并且允许存储功能在切换瞬间增加。所提出的事件触发输出反馈控制器不仅可以保持渐近稳定性，而且可以在某些条件下排除 Zeno 行为。最后，给出了一个数值例子来说明该方法的有效性。
