闭环光纤陀螺中的死区抑制技术研究

Research on Dead Zone Error Reduction Technique in Closed-loop Fiber Optic Gyroscope

研究了闭环光纤陀螺中死区误差的产生机理,并对死区现象进行了仿真。提出了一种消除或减小死区误差的电学方法。实验表明,采用三角波补偿信号可有效抑制闭环光纤陀螺中死区误差。

The mechanism of dead zone error in closed-loop fiber optic gyroscope was studied in this paper, and the phenomenon of the dead zone error was simulated. An electrical method of reduction or elimination this dead zone error was given. As the test data indicates, the compensated triangle wave could effectively restrain the dead zone error in closed-loop fiber optic gyroscope.
