Abstract

State feedback and full order/reduced order measurement feedback controllers are explicitly constructed that solve the H"~ almost disturbance decoupling problems for general linear discrete-time systems. Keys to the explicit construction of these controllers are structural decompositions of the systems and a low gain feedback design technique.
