转台伺服系统的无超调设计

NON OVERSHOOT DESIGN FOR SERVO SYSTEM OF GYRO TEST TURNTABLE

本文通过分析国内外陀螺漂移测试转台伺服系统的现有设计方案,对其伺服系统的无超调设计进行了探讨。最后采用了粗精双回路切换方案,这为提高测试转台的精度和动态性能提供了新的途径。

The non-overshoot design problem of a gyro test turntabl servo system is studied in this paper. After comparing the different control methods used here and abroad, a scheme using two feedback loops to be switched under proper conditions is adopted, This results in higher accuracy as well as better dynamic performances.
