Finite-time Stability of Discrete-time Switched Positive Linear Systems

This paper investigates finite-time stability (FTS) for discrete-time switched positive linear systems (DSPLSs) subject to average dwell time switching by employing multiple linear copositive Lyapunov functions (MLCLFs). MLCLFs are taken in non-quadratic form by using positive states of SPLSs to compensate general results of common quadratic Lyapunov functions. Sufficient conditions of FTS for DSPLSs are established. An illustrative example is given to demonstrate the effectiveness of the proposed method.
