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

โฆ Synopsis
This paper considers the problem of identification of systems characterized by certain parameters. An iterative method for estimating these parameters on the basis of noise-corrupted input-output data is presented.
The problem of identifying parameters of a single-input single-output discrete system is reduced to solving a set of regression equations. The estimates of certain correlation functions appearing as coefficients in these equations are constructed from the input--output data and their convergence with probability one is established using results of time series analysis. An algorithm is presented which approximates the solution of the regression equation and converges with probability one.

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
