Global Stability of a Direct Adaptive Control Scheme With Respect to a Graph Topology

  • Chapter
Adaptive and Learning Systems

Abstract

We study the stability given by a modified model reference adaptive controller. Modifications are projections of the adapted parameters into a convex compact set and normalization of the signals entering the adaptation law by a weighted l 2-norm of the I/O signals. The plant is assumed to satisfy properties which are proved to be robust with respect to a graph topology based on μ-exponential stability. Global stability is established and the mean square tracking error is shown to converge to zero linearly with the unmodeled effects.
