Fuzzy sliding mode control of nonlinear system

Abstract

The unmodeled dynamics of a nonlinear control system is studied by using a fuzzy control approach. Based on variable structure system (VSS) theory, this paper presents two fuzzy control schemes. As the upper bound of system uncertainty is known, it can be used as a clue to form fuzzy control logic. The full inference provides an estimation for the unknown upper bound. Examples are given to illustrate the application of the proposed methods.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
