中文摘要
      本文通过系统的开环极点和闭环极点,给出了单输入最优控制系统中Q矩阵的一种解析表达式.根据这一结果,我们不仅可以求得LQ最优控制指标函数中的Q矩阵,而且还可以将它作为判别LQ逆问题解存在的充分条件.
英文摘要
      This paper presents an analytical solution to the LQ inverse problem for systems with single input control variable in terms of the eigenvalues of both open-loop system and closed loop system. By utilizing this result,the weighting matrices Q and R can be easily obtained,and the sufficient condition for the exsitence of LQ inverse problem is immediate as well.
