This paper addresses the event-triggered dynamic output feedback control for switched linear systems with frequent asynchronism. Different from existing work, which limits at most once switching during an interevent interval, we adopt average dwell time approach without limiting minimum of each subsystem, and thus is allowed to happen in interval. Since difficulty acquiring full information system states, controller taken into account stabilize system. By employing a...
