Positive observer design for switched interval positive systems via the state-dependent and time-dependent switching

摘要

Positive observer design of interval switched positive systems is considered in this paper. The multiple quadratic co-positive Lyapunov functions technique and the method of augmented systems are adopted. The sufficient conditions of insuring stabilization of augmented systems are obtained under the state-dependent and time-dependent switching law, respectively. In the end, a numerical example is provided to demonstrate the feasibility of the presented results.
