摘要
针对一类二阶动力学系统的分散状态反馈特征结构配置问题,在一定条件下,给出了求解所有状态反馈增益阵和特征向量矩阵的参数化方法,其包含的自由参量为控制系统设计提供了全部自由度.该参数化方法直接基于原系统的参数矩阵,因而只涉及n-维矩阵的运算,其简单性为系统设计提供了便利.
Eigenstructure assignment via decentralized state feedback was investigated in a class of second-order dynamic systems. Under certain conditions, the parametric expressions of all the gain matrices and the closed-loop eigenvector matrices were established which offer all the design degrees of freedom. This parametric method directly utilized the original system data, involves computations only on n-dimensional matrices, and was thus simple and offers more convenience in control system designs. An illustrative example showed the effect of the proposed parametric method for second-order dynamic systems.
