2－D系统的干扰解耦

本文讨论了２－Ｄ系统的干扰解耦问题（ＤＤＰ），将１－Ｄ系统理论中的有关结果推广到了２－Ｄ线性离散常系数一般模型（２－ＤＧＭ），得到了问题可解的充分条件和必要条件以及相应的算法．这些结果较好地改进了现有结果

The Disturbance Decoupling Control for 2-D Systems

In this paper,the disturbance decoupling problem (DDP) for 2-D general models (2-D GM)is discussed. In order to extend the corresponding results in 1-D case (see Wonham (1984)) to 2-D systems,the well-known concept of (A,B)-invariant subspace is generalized to the case that permits A to be a nonsquare matrix of some special forms. Based on this new concept,the sufficient conditions to the solvability of the DDP for 2-D GM are presented,and the corresponding design procedures are also proposed. These results have improved well the existing works.
