摘　　要：基于矩量分析,作者提供了一种求单输入线性控制系统极点配置问题的新算法.该算法不仅计算复杂度小于同类算法,而且程序简单,算法通用性好,对极点的重数和极点是否属于矩阵的点谱都不做要求.数值算例表明算法较其它算法具有优越性.A new efficient algorithm for the pole assignment problem of single-input systems is presented in this paper. It is based on the moment analysis. The present algorithm is not only far less complex than the other similar algorithms, but also simple and easy to code, Moreover, it is an universal algorithm, this proposed algorithm performs equally well with distinct and multiple desired poles, and no matter whether the poles belong to point spectral of matrix. Finally, several numerical examples are given to test the new algorithm, the results is satisfactory.
