摘　　要：利用内模控制结构下对象至动态矩阵控制(DMC)闭环特征多项式的系数映射关系,讨论了DMC的闭环特征多项式系数的简洁表达形式.得出了DMC的闭环特征多项式系数的一种快速算法,进而得出了有关闭环系统降阶的新结果.By using the coefficient mapping relationship of the characteristic polynomials between a plant and the dynamic matrix control (DMC) closedloop system, a terse expression of the coefficients of DMC closedloop characteristic polynomial was discussed. A fast algorithm to calculate those coefficients was derived. It also provided some new theoretical results on reducing the closedloop order of DMC system.
