Adaptive Control for Uncertain Nonlinear Systems with Measurement Uncertainty

In this study, the global adaptive control is considered for a class of uncertain nonlinear systems with measurement uncertainty, where the bounds of the measurement uncertainty and system uncertainty are not a priori. A dynamic gain-based control strategy and the feedback domination technique are applied for the controller design, where a set of new dynamic gains is proposed to deal with uncertainties with unknown bounds. It has also been proven that global stability can be achieved under the designed controller. Finally, a simulation example is presented to illustrate the effectiveness of our proposed method.
