Event‐triggered practical finite‐time output feedback stabilisation for switched non‐linear time‐delay systems

This study investigates the event‐triggered practical finite‐time output feedback control for a class of switched high‐order non‐linear time‐delay systems with uncertain control coefficients. A reduced‐order observer is first constructed to estimate the unmeasurable states. By adding a power integrator technique, an event‐triggered output feedback controller is designed for the nominal system. Subsequently, the constructed observer and controller are scaled with a suitable gain by homogeneous domination approach, which, together with an appropriate Lyapunov–Krasoviskii functional, can render that the uncertain switched high‐order non‐linear system with time‐varying delay is practical finite‐time stability. Finally, two examples are provided to demonstrate the validity of the proposed scheme.
