Stability of a Class of Nonlinear System via a Smooth Variable Structure Control
In this paper, a smooth saturation function is defined, a smooth saturation function method is given, and used in the design of variable structure controller for a class of nonlinear system. Owing to its continuity and smoothness, the chattering can be reduced greatly. The trajectory of the nonlinear control system which is globally uniformly ultimately bounded is obtained. Under certain conditions, the asymptotically stability at the origin is given for the nonlinear system. The example shows that the results of the paper are valid and viable.
