Solutions to general H = almost disturbance decoupling problem with measurement feedback and internal stability for discrete - time systems q

In this paper, we construct feedback controllers, explicitly parameterized in a single parameter e, that solve the well-known H = almost disturbance decoupling problem with measurement feedback and with internal stability (H = -ADDPMS) for discrete-time linear systems. In particular, we explicitly construct parameterized solutions for the following three cases: the full state feedback, the full information feedback and the general measurement output feedback. The "rst two cases have static solutions while the last one has only dynamic solutions. Both the full order and the reduced order measurement feedback controllers are presented for the latter case. The problem considered in this paper is general and complete. ( 2000 Elsevier Science Ltd. All rights reserved.
