Robust sliding mode observer design for nonlinear uncertain systems

A robust sliding mode observer is presented in this paper. The design of the observer´s parameters needs not to solve a lot of equations. The observer proposed in the paper is robust to the nonlinearities and/or uncertainties of systems. The convergence rate between the observer and the system can be changed by choosing suitable sliding mode manifold, so that to attain the desired performances. Simulation results are presented to validate the design.
