Design of multivariable adaptive model following control systems

The results for the problems of ''perfect model following'' and ''hyperstability of model reference adaptive systems'' are integrated in order to develop a general design technique for multivariable adaptive model following control systems. Two types of adaptation are involved: adaptation of the parameters of the control loop and signal synthesis adaptation for model following control systems with a fixed structure. The design and the implementation of the adaptation mechanism based on the use of a hyperstable adaptation algorithm are discussed. The feasibility and the advantages of the procedure are illustrated by applying it to a non trivial aircraft control problem.
