摘要
本文在文[5]的基础上进一步提出了有关线性系统模态解耦的一些新概念,并给出了利用状态反馈实现线性系统模态解耦的充要条件和新算法。新算法计算量小,简单有效,且可以给出实现模态解耦的反馈律及其对应的闭环特征向量矩阵的全体。通过对文[5]中的非旋转式导弹系统进行模态解耦设计,说明了算法的应用过程及其简单、有效性。
Some new concepts about modes decoupling for linear systems are proposed on the basis of ref. [5], necessary and sufficient conditions as well as a simple and effective algorithm for modes decoupling control of linear systems via state feedback are also obtained. The obtained algorithm requires less computational work, and can give all the feedback laws which realize the modes decoupling reqirement, together with the eigenvector matrices of the corresponging closed loop systems. By using this algorithm, the modes decoupling control design for the unrotating missile which was studied in [5] is carried out. The designing process shows the simplicity and the effect of the approach.
