Abstract: In this Paper, the optimal control problem of multivariable ration systems is discussed under the\state-space description. Then, a normalized optimal control model is established, Finally, a generalprocedure for the modelling is proposed.

Key words: ratio system, optimal control modelling, desired ratio, normalized model

摘要： 本文在状态空间描述意义下讨论多元比值系统最优控制问题的提法。文中在阐述多元比值系统最优控制问题的基础上，建立了规范结构最优控制模型，并对建模方法作了讨论。
