Interval Observer Design For Discrete-Time Switched System

In this paper, the problems of interval observer design for discrete-time switched system are investigated. In order to make the residual system stable and non-negative, a time varying linear transformation and a standard switched system stability analysis are used. Based on these, an interval observer for discrete-time switched system is constructed. A simulation example is given to illustrate the effectiveness and correctness of the proposed method.
