Sufficient conditions for arbitrary pole assignment by constant decentralized output feedback
ABSTRACT This paper examines the problem of arbitrary pole assignment by decentralized output feedback. New sufficient conditions for the existence of real solutions are derived in terms of the heights of the first Whitney classes corresponding to the channel pairs ofm
i outputs, pi inputs, and some appropriate partitioning of the number of states. These results extend the odd intersection framework approach based on the heights to the decentralized case and provide sufficient conditions for cases not covered by previous results.
