STRUCTURAL-PROPERTIES OF COLUMN (ROW) REDUCED MFDS

Certain Matrix Fraction Descriptions (MFDs) are shown to possess impor tant structural properties in their ability to display the infinite po le (respectively zero) structure of a rational transfer function matri x. Among a number of results, two algorithms are developed, the combin ation of which produce such an MFD displaying the complete infinite fr equency structure of a rational transfer function matrix; and a simply checked necessary and sufficient condition for when the given MFD dis plays the complete infinite pole-zero structure information is provide d.
