摘 要：对聚合化学反应中的连续搅拌反应釜反应-换热网络(CSTR）的动力学模型进行了分析。利用相对增益矩阵法(RGA)，准确地确定出了这个复杂网络的控制量与被控量的最佳搭配，并设计了控制方案，然后，分别在不同的时间尺度上,对有关文献中已得到的降阶模型设计了控制器。仿真结果表明，与不分时间尺度设计的控制器比较，采用该方案能简化控制器的设计，并可得到更快速、准确、抗干扰性更强的控制效果。

Abstract: The dynamic model of continuous stirred tank reactor (CSTR) reactorheat exchanger networks was analyzed. The relation gain array (RGA) method to find the best pair between the control variable and controlled variable was applied, the control plan was designed, then controllers on different time scales to control on the basis of the reduced order model from related reference were designed. Simulation and experimental results indicate that the plan proposed reduces the design of the controller and gets quicker, more accurate and better resistance behaviors.
Key words: multitime scale; process control; continuous stirred tank reactor (CSTR); reactorheat exchanger network; relation gain array (RGA)
