This paper studies the structural properties of both ÿnite poles and the inÿnite pole of linear time-invariant singular systems under output feedback. Three main problems are studied, namely, (1) the algebraic structures of both ÿnite poles and the inÿnite pole; (2) the assignability of ÿnite poles and the elimination of the inÿnite pole by output feedback;(More)
We certify that we have read this thesis and that in our opinion it is fully adequate in scope and quality as a thesis for the degree of Master of Science in Electrical and Electronic Engineering. ABSTRACT For the application of UPS inverters. The aim of the UPS is to provide the necessary loads with a sinusoidal output voltage at low harmonic distortion.(More)
