On Checking Null Rank Conditions of Rational Matrices

Abstract

In this paper we discuss possible numerical approaches to reliably check the rank condition rank $G(\lambda )=0$ for a given rational matrix $G(\lambda )$ in terms of its descriptor system realization. For test purposes we employ functions available in the Control System Toolbox of MATLAB and the Descriptor System Tools (DSTOOLS) collection.
