民机地面滑跑建模与仿真

摘要

Model and simulation problems of civil aircraft taxing are researched in this paper. Normal and Faulty models of landing gears were studied mainly, and a solution for speed oscillation was proposed. After that, the system model was setup based on Simulink. The simulation results showed that the proposed model and solution can simulate the movement of civil aircraft taxing correctly, based on which control design and simulation of ground operation can be performed.%研究了民机地面滑跑过程中的建模和仿真问题。主要对起落架在正常及其故障情况下的建模进行了深入研究，并针对数字仿真过程中出现的速度震荡问题提出了一种解决方法，在Simulink中实现模型并进行仿真。结果表明本文所建立的模型和提出的方案能够正确反映民机地面滑跑时的运动状态，为进一步进行控制律设计和地面运行仿真奠定了基础。
