This technical note considers the problem of reliable disturbance decoupling for a generalized multichannel system in a game-theoretic framework. Specifically, we link the problem of stabilization of the multi-channel system to certain properties of controlled invariant subspaces that are associated with the problem of disturbance decoupling, where the structure induced from this family of inva...
