Design of sliding mode observer for uncertain nonlinear systems

This paper takes a detailed discussion about a class of nonlinear systems with uncertainty and Lipschitz part. In the particular systems, the nonlinear part satisfies the Lipschitz condition, while the uncertain part is a bounded function. A design of nonlinear sliding mode observer is then developed, with which the system stability is fully proved. Simulation studies are presented to demonstrate the effectiveness of the proposed strategy.
