Abstract

Recently we have developed concurrent learning model reference adaptive controllers which use recorded data concurrently with current data and can guarantee exponential stability of the closed loop without requiring persistency of excitation. The rate of convergence of these controllers is dependent on the quality of the recorded data, particularly the minimum singular value of the matrix containing the recorded states. In this paper, we use a Lyapunov framework to integrate a singular value maximizing data recording algorithm with concurrent learning adaptive controllers.
