Abstract:

Adaptive parameter estimation and adaptive control have been well developed to achieve modeling and control for uncertain systems. However, the well-known parameter estimation and adaptive control methods have been mainly designed based on the gradient algorithms (with appropriate modifications) by using the prediction error or control error. Hence, the parameter estimation convergence and the online verification of the required persistent excitation (PE) condition are generallydifficultwith this framework. In this talk, we will introduce a novel robust, fast adaptive parameter estimation framework, where the estimation error between the unknown parameters and their estimates are explicitly obtained and then use to drive online adaptation algorithms. This new adaptation even allows to achieve finite-time parameter estimation, and can be easily incorporated into adaptive control designs to achieve tracking control and parameter estimation simultaneously. We will also introduce an intuitive and numerically feasible approach to online verify the PE condition. Finally, several practical application of this new adaptation to in-car parameters estimation, ITER cryogenics system identification, and adaptive control for robotics, wave energy converters (WECs) and other realistic systems will be presented.
