GST-1型三轴台精密位置状态的实现

Implementation of Precise Position of GST - 1 Three Test Table

现代惯性系统的综合测试中，转台的位置精度是一项关键指标,为设计高精度的位置控制系统，本文采用双回路位置控制，保证了系统的动态性能和精度．特别是对精密位置的关键环节—比相环节进行了深入分析研究，进一步提高了万分位上的位置数据的稳定性．

In the spothesis test of modern inertial system, the position accuracy is the key to the test table. So thedouble loop position control is adopted for high accuracy position system, which ensures dynamic performance andhigh accuracy. Particularly, the key link-phase detecting of precise position is carefully considered so that 0.0001°position data stability is improved.
