中文摘要：
理论上分析了谐振式陀螺系统中的传输特性和正弦波调制特性。为了实现谐振频率的跟踪锁定，设计并搭建了谐振频率跟踪锁定试验系统。通过正弦波调制、解调得到了谐振频率跟踪锁定需要的鉴频曲线。利用PID反馈控制电路和得到的鉴频曲线实现了谐振频率的跟踪锁定，并进一步评估得到了谐振频率跟踪锁定的精度和稳定度。为光学微谐振腔的谐振频率跟踪锁定技术的深入研究提供了参考。
英文摘要：
The transmission characteristics and sine modulation characteristics were theoretically analyzed. In order to achieve track-locking of the resonance frequency, a test system of resonant frequency tracking and locking was designed and built. Sine wave modulation and demodulation were used to obtain the error signal of resonance frequency track-locking. Combining PID feedback control circuit with the error signal, the resonant frequency track- locking was realized, and further the accuracy and stability of the resonant frequency track- locking were assessed.
