Sliding-mode observers based on equivalent control method

Abstract

The sliding-mode observer for a nonlinear system is proposed. The observer is based on the equivalent control method. Compared with the known output global linearization approach it is given in terms of the system variables and does not require nonlinear state transformation. Several examples are presented which illustrate the proposed method.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
