Finite-time stabilization of high-order output-constrained switched systems via state feedback

In this paper, finite-time stabilization of high-order switched systems with output constraints via state feedback control laws is investigated. Incorporating a common tangenttype barrier Lyapunov function, state feedback controllers are presented in a systematic way by revamping the adding a power integrator approach. With the designed state feedback controllers, switched systems are finite-time stabilized and the output constraint is also guaranteed at the same time. The method is proposed in a unified frame because that it can handle finite-time stabilization problem of high-order switched systems with/without output constraints both, no need of changing switched state feedback controllers' structure.
