摘要
A new approach to design interval observers for a class of nonlinear systems is proposed in this paper.Based on the matrix theory,a simple elementary operation is given to find a positive realization for the systems with bounded uncertainties.Compared with previous works,the main contribution of this work is to provide a method to guarantee the existence of an observer gain by means of such a positive representation.Finally,a numerical example is provided to demonstrate efficiency of the proposed approach.
