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…
Squaring-Up Method In the Presence of Transmission Zeros
Zheng Qu, Daniel Wiese, Anuradha M. Annaswamy +1
This paper presents a method to square up a generic MIMO system that already possesses transmission zeros. The proposed method is developed based on and therefore can be incorporat…
Closed-loop Reference Models for Output-Feedback Adaptive Systems
Travis E. Gibson, Anuradha M. Annaswamy, Eugene Lavretsky
Closed-loop reference models have recently been proposed for states accessible adaptive systems. They have been shown to have improved transient response over their open loop count…
Adaptive Systems with Closed-loop Reference Models: Stability, Robustness and Transient Performance
Travis E. Gibson, Anuradha M. Annaswamy, Eugene Lavretsky
This paper explores the properties of adaptive systems with closed-loop reference models. Using additional design freedom available in closed-loop reference models, we design new a…
