摘　　要：半球谐振陀螺(HRG)幅度控制环路用于陀螺的振动激发和振动幅度维持,工作于力反馈模式的半球谐振陀螺,其标度因数与陀螺振动幅度成正比。该文对半球陀螺力反馈模式工作原理进行了理论推导,然后分析了传统幅度控制方式受外界温度变化、电子元器件老化等原因影响,将会导致半球陀螺标度因数发生变化,最后提出了半球陀螺幅度控制的优化方法,在实现相同标度因数稳定性的的情况下,大幅降低电路实现难度。The amplitude controlloop of hemispherical resonator gyroscopes(HRG)is used for vibration excitation and amplitude maintenance of HRG.The scale factor of HRG working in force-to-rebalance(FTR)mode is proportional to the amplitude of vibration.In this paper,the working principle of HRG working in FTR mode is theoretically deduced,Then,it is analyzed that the traditional amplitude control method will change the scale factor of the hemispherical gyroscope due to the influence of external temperature change and aging of electronic components.And finally,the optimization method of HRG amplitude control is proposed,which can greatly reduce the difficulty of realizing the circuit under the condition of achieving the same scale factor stability.
