Systems Seminar
Analysis of Feedback Systems with Non-Strictly-Proper Loop Gain
Prof. Dan Cobb
UW ECE Dept.
Abstract
Most conventional feedback theory for lumped linear systems is
based on the assumption that the loop gain is strictly proper. However,
certain aspects of known theory do impinge on the non-strictly-proper case.
These include biproper and singular state-space theory and the
Q-parametrization of stabilizing compensators. In the first part of our
talk, we will examine these constructions and describe a fundamental flaw
in their conclusions for the non-strictly-proper case. Next, we will
propose a new analytical approach to problems with arbitrary proper loop
gain. Finally, our results will be used to augment and correct the
constructions listed above.
Time and Place: Wed., Mar. 29, 3:30-4:30 pm in 4610 Engr. Hall.
