用光电综合负反馈补偿IFOG的零漂

COMPENSATING IFOG'S ZERO DRIFT BY OPTIC-ELECTRIC NEGATIVE FEEDBACK

提出一种新的零漂补偿方法──光电综合负反馈法。该法利用一种特殊结构，将IFOG系统的零漂准实时测出，并通过光电综合负反馈抑制零漂。计算机仿真和实验结果证明了该方法是有效的。

A novel optic-electric negative feedback method for compensating zero drift was put forward in this paper. A special compensating loop was designed to detect the interferometric fiber optic gyroscope's (IFOG) zero drift, in quasi-realtime and the measured value of zero drift was negatively fed back by optic-electric component to restrain zero drift. Computer simulation and experimental result indicated that thls method is effective to compensate IFOG's zero drift.
