摘要：

This paper presents a sliding-mode controller for a class of nonlinear discrete-time systems. The proposed controller uses a modified switching function that produces a low-chattering control signal. In order to improve the controller performance, an adaptive term is added to the original sliding- mode algorithm. This new feature uses an artificial neural network for online Identification of the modeling error. Simulations and experimental results illustrate the main characteristics and performance of this approach.
