动力调谐陀螺仪脉冲数字再平衡回路中的量程转换

Dual-Factor Switching in Pulse Rebalance Loop for Dynamically-Tuned Gyroscope

本文从理论上对回路的极限环进行了分析，并作了相应的仿真，结果表明，对于Ｉ型系统来说，采样频率低于８ＫＨｚ时，系统不存在极限环。本文还在设计双刻度开关逻辑的基础上，通过对回路的数字仿真，确定出量程转换时所选用的合适阈值。

The limit cycle has been analyzed theoretically in this paper and the corresponding simulation has been made. The result shows that there is no limit cycle when the sampling frequency is below 8 KHz for system of type I. Based on the dual-factor switching logic design, the suitable threshold values adopted for switching have been determined through digital simulation.
