Abstract
We formulate and solve a pole placement problem by state feedback for overdetermined 2D systems modeled by commutative operator vessels. In this setting, the transfer function of the system is given by a meromorphic bundle map between two holomorphic vector bundles of finite rank over the normalization of a projective plane algebraic curve.
The obstruction for a solution is given by an existence of a certain meromorphic bundle map on the input bundle. Reducing to the 1D case, this gives a functional obstruction which is equivalent to the classical pole placement theorem.
Our result improves on, and gives a new approach to pole placement even in the classical case, and answers a question of Ball and Vinnikov. (C) 2020 Elsevier Inc. All rights reserved.
