摘要
基于对某型飞机机械式飞行操纵系统结构的分析,针对其方向舵操纵通道,利用等效动态模型法建立了其混合式操纵系统完整的数学模型,其中对软式传动机构部分采用了一种新的等效建模方法。通过在MATLAB环境下的数字仿真与降阶处理,得到与实际系统静态、动态响应相吻合的模型。该模型可以进一步经过处理而得到系统的等效线性模型,将可用于操纵系统自身特性的分析,及整个飞机飞行品质的研究中。
To one of a vehicle hybrid control system,a complete mathematics model is established by using the equivalent dynamic method,after analyzing the rudder mechanical structure of it.And a new modeling method is applying to the flexible drives part of it.By using Matlab/Simulink,the simulation results show that the model is identical to the real system in both static and dynamic performance.In case of working more on the model we get,the performance of the vehicle control system and the whole aircraft including it could be analyzed easier.
