Optimization and Systems Theory
Do stabilizable plants admit a coprime factorization?
The stabilization problem in control theory is the following:
given an unstable plant, find a controller, such that the
overall transfer function of their feedback interconnection
It is known that plants possessing a coprime factorization
are stabilizable. This raises the natural question in the title.
It is also known that if the ring of stable transfer functions
under consideration is projective free, then the answer
to the question is yes. In this talk we will show that common
classes of stable transfer functions are indeed projective free.
(This is joint work with Alexander Brudnyi from the
University of Calgary, Canada.)
