本文应用闭坏系统的特征值与特征矢量的局部配置的方法来设计系统。在设计过程中,利用多输入系统解的非唯一性,按使闭环特征值灵敏度最小的原则确定最佳常值状态反馈。采用这种方法,可以对闭环矩阵特征矢量的某些元素进行配置,从而对影响状态响应的形状提供了途径。数值例子说明,该方法还具有适用范围广,计算结果好等优点。 In this paper, the system is designed by using the eigenvalue of the closed system and the local configuration of the eigenvector. In the design process, the non-uniqueness of the solution of the multi-input system is utilized, and the best constant state feedback is determined according to the principle of minimizing the sensitivity of the closed-loop eigenvalue. In this way, some elements of the closed-loop matrix eigenvectors can be configured to provide a way to influence the shape of the state response. The numerical example shows that the method has the advantages of wide range of application, good calculation results and so on.
