摘要: 本文以Purex流程1A槽萃取段为对象,通过萃取过程机理分析和实验数据拟 合相结合的方法,提出了一种适于最优控制应用的带有动态补偿项的静态机理模型 和有关最优控制的限制条件;在定点和浮点线性化的基础上,建立了适合于该萃取 过程的线性规化约束条件和目标函数;拟定了一种最优控制方案,用微型机进行最 优控制系统的数字仿真研究,取得了满意的结果.Abstract: In this paper, taking the extractive section of tank 1A as the object, a static stage model with dynamic compensator suitable for optimal control and limiting condition are presented through the method of combining theoritical analysis with experimental fit. On the basis of fixed and floating linearization the performance function and constraint condition of linear programming for extractive process are developed. The strategy of optimal control is drawn up. Digital simulation of the optimal control system is investigated and satisfactory results are obtained.
