Improved event-triggered control for a class of continuous-time switched linear systems

Both state-based and observer-based output feedback event-triggered controls for continuous-time switched linear systems are studied. An improved event-triggered sampling mechanism is adopted in feedback control, under which Zeno behaviour can be easily excluded in sampling process. Meanwhile, it is...

Description
Summary:Both state-based and observer-based output feedback event-triggered controls for continuous-time switched linear systems are studied. An improved event-triggered sampling mechanism is adopted in feedback control, under which Zeno behaviour can be easily excluded in sampling process. Meanwhile, it is shown that the closed-loop switched system is stable in the sense of global uniform boundedness satisfying an average dwell time condition. A numerical example is finally given to verify the developed results.
