✦ Synopsis
An adaptive controller needs supervisory functions in order to function well in an industrial environment. This paper describes these needs, and provides examples of supervisory functions that presently are used in industrial adaptive controllers. These supervisory functions ensure that adaptation only is performed when proper excitation is available. Supervisory functions that prohibit adaptation during the "rst phase of a load disturbance response, during signal saturation and oscillations caused by nonlinearities are also proposed.

Minimum variance adaptive control schemes are considered. By means of the concept of excitation subspace, the notion of effective identification algorithm is introduced. It is shown that, if the system to be controlled is noise-free and minimum phase, the tracking error tends to zero provided that t
In order to facilitate the utilization of single-chip microcomputers for adaptive control some extremely simple algorithms have been developed. The simplicity has been achieved by using performance criteria based on geometrical properties of the control error process while the adaptation acts like a
