Abstract

An asymptotic observer design procedure is analyzed for discrete-time switched linear systems with exogenous, arbitrary, and unknown mode sequences. The observer consists of two parts: a mode detector, and a continuous observer. It is shown that, under mild conditions, the proposed scheme results in a global asymptotic observer for almost all initial states.
