摘要

摘要: 针对现有冻结站盐水流量和温度控制方法存在控制精度低的问题，提出了一种盐水流量和温度的模糊解耦控制方法。首先根据盐水流量和温度控制精度的不同，采用模糊控制法对流量和温度进行模糊控制；然后分析和研究盐水流量和温度间的耦合关系，采用解耦控制法对模糊控制输出的流量和温度进行解耦控制。仿真结果表明，该控制方法无需对盐水流量和温度建立精确数学模型，可实现盐水流量和温度的解耦控制，控制精度高。

Abstract: In view of problem of low control precision of existing control method of brine flow and temperature in frozen station, a fuzzy decoupling control method of brine flow and temperature was proposed. Firstly, fuzzy control method was carried out on fuzzy control of flow and temperature according to different control accuracy of the brine flow and temperature. Then the decoupling control method was used for decoupling control of output flow and temperature through analysis and research of the coupling relationship between brine flow and temperature. The simulation results show that the control method can realize decoupling control of brine flow and temperature, and has high control precision without accurate mathematical model of brine flow and temperature.
