Abstract

This paper focuses on the development of a wavelet based adaptive sliding mode control strategy for a classof discrete time uncertain nonlinear systems. An adaptive sliding mode control is utilized to assure the stabletracking of uncertain nonlinear system under consideration. Wavelet neural network (WNN) is used to mimicthe uncertainties present in the system. Proposed scheme is derived to guaranty the necessary and sufficientreaching condition for sliding mode control in presence of modeling uncertainties and mathematicalinaccuracies. A numerical example is provided to verify the effectiveness of theoretical development.Keywords: Adaptive sliding mode control; wavelet networks; discrete time nonlinear systems.
