Adaptive control for uncertain systems with sector-like bounded non-linear inputs

Abstract

In the current paper, a model reference adaptive controller design based on hyper-stability theory is proposed for the uncertain non-linear system equipped with the so-called sector-like bounded non-linear inputs, which are subject to system uncertainties of the norm-bounded system parameter variations and external disturbances. The control objectives are to achieve an asymptotical tracking of the system output targeted to the desired reference model output and to ensure the bounded condition of all the signals in the controlled system. Finally, some computer simulation results are given to validate the excellent performance of the proposed adaptive control system.
