摘要
以新型飞机除冰车加热系统为研究对象,通过分析实验数据,首次提出了除冰液流量全量程范围内的加热系统数学模型,并综合应用模糊理论设计Fuzzy自整定PID参数的Smith预估控制器。MATLAB仿真结果表明,应用这种方法设计出的控制策略能较好地适应飞机除冰车模型参数的大幅度变化,并具有良好的稳态精度和自适应能力。
This paper presents our research on the heating system in a new aircraft deicing vehicle, Through analyzing the data of experiments, a new idea of building a full range-flow mathematical model of heating system is put forward for the first time. By making comprehensive use of fuzzy theory,a fuzzy self-tuning PID Smith controller is also designed, The result of simulation on computer with MATLAB shows that the control strategy designed this way can better adapt the large range of changing in the aircraft deicing vehicle model and has good stability precision and self-adaptive property.
