Sliding control of non-linear systems containing time-varying uncertainties with unknown bounds. (English)
[J] Int. J. Control 74, No.3, 252-264 (2001). ISSN 0020-7179; ISSN 1366-5820/e

A class of single-input non-autonomous nonlinear systems is considered in the presence of unknown time-varying uncertainties and disturbances with unknown bounds. A sliding controller is designed with adaptive laws to give proper tracking performance. The controller design procedure consists in two steps. First, a feedback control is constructed to make the sliding surface attractive. Next, the uncertainties and disturbances are estimated by using a finite-term Fourier series approximation. Some simulation results are also presented.
