Decoupling of Multivariable Control Systems over Unique Factorization Domains
K. B. Datta, M. L. J. Hautus · SIAM Journal on Control and Optimization · 1984
Necessary and sufficient conditions are established for the existence of a state variable feedback decoupling of an m-input, m-output time invariant linear control system over a unique factorization domain. An explicit computation is provided for the feedback and the feedforward gain matrix. Also necessary and sufficient conditions for the existence of a stability-preserving state feedback decoupling are given. The results are illustrated by some examples.
