论电子调整在飞控系统RVDT精度控制的应用

Study of Electrical Rigging for Flight Control System RVDT Accuracy Control

介绍了旋转可变差动变压器Rotate variable differential transformer(RVDT)的工作原理,分析了RVDT的误差来源和分布规律。随即针对其误差特点,讨论了电子调整在飞控系统RVDT精度控制方面的应用。最后通过试验证明电子调整的效果。

This article introduced theory of Rotate variable differential transformer （RVDT） ,analyzed the typical errors root cases and their distribution law. Towards these errors characteristic, a valuable method ＂Electrical Rig＂ is introduced to increase RVDT accuracy. At last, validate this method by test include the comparing curve between unrigged and rigged RVDT degree.
