Abstract

This paper considers the design and analysis of online approximation based controllers for a general class of uncertain nonlinear dynamical systems. An adaptive bounding design is used to show that the overall online approximation based control system guarantees semi-global uniform ultimate boundedness within a neighborhood of zero tracking error. The theoretical results are illustrated through a simulation example
