摘　　要：针对飞机防除冰试验研究需求,设计了适用于大型结冰风洞的多功能电加热控制系统。通过可编程控制器(PLC)与上位机远程交互,实现控制律开环和主回路通断、连续调压闭环温度控制,以满足不同飞机型号电热防/除冰电源制式和控制模式的要求。针对反独热编码控制律任意性的特点,设计控制律程序,并进行了型号模型结冰风洞电热防冰试验,结果表明系统运行稳定性好、可靠性高,应用效果好。相关研究的开展可为电加热控制系统设计及研究提供参考依据。For aircraft anti-icing and de-icing test research needs,a multi-functional electric heating control system for large icing wind tunnel was designed.Through the remote interaction between PLC and the master computer,the control law open loop,on/off,continuous voltage regulation and closed loop temperature control were realized,so as to meet the requirements of the electric heating anti-icing power system and control mode of different aircraft models.In view of the arbitrariness of the control law for anti-one-hot coding,the control law program was designed,and the electric anti-icing test was carried out on the type model of icing wind tunnel.The results show that the system has good running stability,high reliability and good application effect.The development of related research can provide reference for the design and research of electric heating control system.
