A remark on "Disturbance decoupling for linear time-invariant systems: A matrix pencil approach"
In the above paper, an approach was proposed for the disturbance decoupling for the linear system. Some details in the proof of the sufficiency of Theorem 2 for the existence of the matrix F-1 are omitted. In this note, we will give a detailed proof.
