Abstract :
This paper provides some new developments in the design of robust local unknown input observers for nonlinear systems based on first order Taylor approximation. The necessary and sufficient conditions for the existence of the observer are given. A numerical example is given to illustrate the attractiveness and the simplicity of the new design procedure.
