The disturbance decoupling problem with measurement feedback and stability for systems with direct feedthrough matrices

摘要

In this paper the known results on the disturbance decoupling problem with measurement feedback and internal stability (DDPMS) are extended to include non-zero direct feedthrough matrices. Necessary and sufficient for the solvability of the DDPMS are expressed in three subspace inclusions.Keywords: disturbance decoupling, geometric approach, measurement feedback.
