Parameter Estimation in Adaptive Control of Time-Varying Systems Under a Range of Excitation Conditions
Joseph E. Gaudio, Anuradha M. Annaswamy, Eugene Lavretsky +1
This paper presents a new parameter estimation algorithm for the adaptive control of a class of time-varying plants. The main feature of this algorithm is a matrix of time-varying…
Adaptive Flight Control in the Presence of Limits on Magnitude and Rate
Joseph E. Gaudio, Anuradha M. Annaswamy, Michael A. Bolender +1
Input constraints as well as parametric uncertainties must be accounted for in the design of safe control systems. This paper presents an adaptive controller for multiple-input-mul…
Connections Between Adaptive Control and Optimization in Machine Learning
Joseph E. Gaudio, Travis E. Gibson, Anuradha M. Annaswamy +2
This paper demonstrates many immediate connections between adaptive control and optimization methods commonly employed in machine learning. Starting from common output error formul…
Convergence Properties of Adaptive Systems and the Definition of Exponential Stability
Benjamin M. Jenkins, Anuradha M. Annaswamy, Eugene Lavretsky +1
The convergence properties of adaptive systems in terms of excitation conditions on the regressor vector are well known. With persistent excitation of the regressor vector in model…
