摘要
谐振式光纤陀螺是一种基于光纤环形谐振腔Sagnac效应的新型惯性传感仪器。与现有的其他类型陀螺相比,具有很多性能上的优势。在此提出了一种基于DSP技术的全数字闭环方案,并为这种方案建立了数学模型。借助用z变换表示各个环节的离散传递函数,设计并优化了跟踪谐振频率的算法,并将此算法在DSP中实现。
Resonator fiber optic gyro (R-FOG) is a new kind of inertial sensor based on Sagnac effect. Compared with other kinds of gyros, R-FOG has many advantages. Close-loop operation with digital signal processor (DSP) is presented. The mathematical model is established too. Using the Z-transform to describe the discrete transfer function for elements in the system, a frequency-tracking algorithm is designed and optimized, which has been realized in DSP.
