Abstract

Algorithms for the formation of a procedure for the stable estimation of parameters matrices and covariances of perturbation vectors in indefinite dynamic systems based on the concepts of matrix pseudo-inversion are given. For stable pseudo-inversion, the matrix partitioning method is used using simplified regularization. The above algorithms allow for a stable estimation of the matrix of parameters and covariances of the perturbation vectors in dynamic systems and thereby increase the accuracy of adaptive control systems operating in parametric and signal uncertainty conditions.
