摘　　要：气象风洞是模拟流体动力学的实验装置,用于大气和飞行器状态的研究,需对其热供交换系统的运行参数快速精确控制,针对其系统监控,采用可编程序控制器模块(S7-300 PLC)构建硬件系统,采用自适应PID控制策略补偿建模不确定性和干扰,并设计人机一体化的用户控制操作界面(HMI),实现快速准确控制热供交换室温度、流量、压力以及泵、阀等输出设备的状态。实际测试表明:系统运行稳定,控制目标满足设计工艺要求。The meteorological wind tunnel is to simulate fluid dynamics,as an experiment device,used in the state study of atmosphere and aircraft. The operation parameters of device heat exchange system needs to be real-time monitored. For supervising it,programmable logic controller（ S7-300 PLC） was applied in this paper to build the hardware system and the adaptive PID control strategy was applied to compensate the modeling uncertainties and disturbance,the man-machine integrated user control interface（ HMI） was designed,achieving accurately control the heat exchange chamber temperature,flow,pressure and the state of system output,such as pumps,valves. Through testing,the design system runs stable,and meets the design requirements.
