摘要
飞机除冰车是冬季冰雪天气下保障飞机安全飞行的重要设备,除冰车加热与喷射系统管路压力波动对除冰车加热温度控制和安全作业造成影响。在给出除冰车工作原理的基础上,分析了造成除冰车管路系统压力波动的因素,研究了除冰车管路系统压力控制的方法,建立了基于模糊控制和变频调速的管路系统压力控制方法,以克服管路系统压力波动和非线性因素。通过实验平台验证了设计方法的有效性,为工程设计提供了参考。
The aircraft deicing vehicle is an important equipment for secure flying in severe weather of winter. The pipeline pres- sure of aircraft vehicle will effect temperature control on deicing fluid and probably results in security case. The reasons which caused pipeline pressure fluctuating were analyzed according to the work principle of aircraft deicing vehicle. The control methods based on fuzzy control and frequency conversion drive were given to overcome the non-liner and pressure fluctuating for pipeline. The design schemes were accomplished successfully on experimental platform.
