摘　　要：冻结站制冷盐水循环系统盐水流量和盐水温度之间存在强耦合非线性关系,针对这一问题提出模糊补偿解耦控制方法。根据冻结壁与地层热交换所需制冷量以及盐水的流量与温度控制要求,设计盐水流量和温度的模糊控制器;然后根据盐水的流量和温度耦合关系,通过补偿解耦控制器进行解耦;最后结合专家经验实现盐水的流量和温度模糊补偿解耦控制。仿真结果表明,利用模糊补偿解耦这一策略,能较好地实现盐水的流量和温度智能控制。There is a strong interferential and non-linear relationship between flow and temperature of the freezer refrigeratory brine. A fuzzy compensative decoupling control method is put forward for this issue. According to the cooling capacity required for thermo-exchange between frozen wall and stratum and the control requirements of brine flow and temperature, the fuzzy controllers are designed. The decouplers are designed according to the coupling relationship between brine flow and temperature for compensative decoupling. Finally, the fuzzy compensative coupling control of brine flow and temperature is realized in combination with expert＇ s experiences. The simulation results show that the fuzzy compensative coupling strategy makes better intelligent control of freezer＇ s brine flow and temperature.
