摘要
对常值输出反馈极点指定作了研究,给出一种用优化目标函数来求解实现极点指定的输出反馈阵的方法,推证了闭环矩阵的乘方阵的迹对输出反馈阵的导数公式,对目标函数作了改进,使之适用于高阶系统,给出了一个选取初始迭代值的简单而有效的方法,最后的数值例题说明本文的方法是实用的.
Pole assignment with a constant output feedback matrix for a linear system is approached.Based on the relationship between the trace and the eigenvalues of a closed loop system.a performance index is defined, by which an optimal iterative algorithm can be used to obtain the output feedback matrix for pole assignment.An effective selection for initial values of the algorithm is also discussed.
