Model reference adaptive buffering control and co-simulation of magnetorheological aircraft landing gear

基于虚拟样机技术构建了某型飞机起落架缓冲系统动力学模型,提出一种基于模型参考自适应控制的磁流变飞机起落架缓冲控制方法,设计了基于Matlab/Simulink的磁流变飞机起落架模型参考自适应缓冲控制联合仿真模型,定义了数据交换接口,完成了某型号飞机起落架落震缓冲过程的力学与控制的联合仿真验证,通过基于模型参考自适应控制的飞机起落架缓冲系统与传统被动式油液式缓冲系统的缓冲效果对比分析,验证了提出的基于模型参考自适应控制的飞机起落架磁流变缓冲系统替代油液式缓冲系统的可行性与良好的减震效果。

In this paper,the dynamic model of buffer system for a certain type of aircraft landing gear w as built based on the virtual prototype technology,and a buffering control method for magnetorheological landing gear w as also proposed based on model reference adaptive control. A co-simulation model of model reference adaptive buffering control of M R aircraft landing gear w as further designed based on the M atlab/Simulink and the data exchange interface w as defined. The co-simulation model w as verified for a process of drop-test buffering. The comparison of the results from buffering system of landing gear based on model reference adaptive control and the traditional passive oil buffering system show s that the proposed buffering system is feasible and has a good damping effect.
