Balanced stochastic realizations
This paper deals with the structure of balanced solutions to the positive real and the dual positive real equations. The major result is a product or cascade decomposition of the associated spectral factors. It is shown how this result can be used to determine the number of left half plane, right half plane, and imaginary axis zeros of spectral factors without reduction to the regular case. A brief history of balancing and a complete bibliography are presented.
