Abstract: The problem of designing another switching law for the candidate controllers is considered when the switching signal of the switched system is unavailable. The goal of the paper is to ensure the stability of the closed-loop system by choosing the proper candidate controller all the time. A result concerning how to design the stabilizing switching law of candidate controllers is presented for switched nonlinear systems by means of the properties of strictly passive systems. The effectiveness of the proposed method is tested by a nonlinear example.
