摘要
本文给出了线性定常二次型最优离散系统的两个必要条件,得到了单输入单输出系统开环特征多项式系数a_i和最优闭环特征多项式系数b_i与权阵Q之间的直接关系,所得结论有益于设计一个具有指定闭环极点的最优控制系统。
Two necessary conditions are given for linear constant quaduatic optimal discrete systems in this paper. The direct relation between the coefficients, of the open-loop systems, the coefficiertte of the optimal closed-loop systems and the weighting matrix Q is obtained for SISO systems. The obtained result is significant for designing a optimal control system with prescribed closed-loop poles.
