摘要
对六自由度飞行模拟器台架系统进行了动力学分析，发现运动平台作用于各液压伺服缸上的模态质量是变量，提出采用结构不变性和复合控制的方法来补偿模态质量变化对系统的影响。实验结果表明，这些方法对提高系统的静态、动态品质有明显的效果。
It is discovered that the simulating status mass applied to hydralic cylinders by the moving table is changeable through the dynamic analysis for six-degree of freedom flight simulator. It is possible to compensate the effect of the change of the simulating status mass on the system by using the principle of unchanged structure and complex control.The testing result shows that these methods have obvious effects on the increase of the system's static/dynamic quality.
