Adaptive Robust Control Schemes for a Class of Uncertain Systems with Partial Knowledge of Uncertainty Bounds

Abstract

The problem of robust stabilization of a class of uncertain dynamical systems with partial knowledge of uncertainty bounds is considered. A class of continuous adaptive robust state feedback controllers are proposed which can guarantee the uniform ultimate boundedness of the resulting closed-loop dynamical systems in the presence of the uncertainties. Here, the proposed state feedback is, instead of saturation-type, uniformly bounded and uniformly continuous.
