温度变化严重影响了杯形陀螺的使用精度,为了消除或减小温度对杯形陀螺性能的影响,首先从理论上分析了温度对陀螺性能的影响机理,在此基础上提出了一种基于陀螺内部信号对杯形陀螺进行温度补偿的方法；通过大量的温度实验,从工程应用实际出发,分别建立了陀螺的零偏-温度、零偏-驱动电压以及零偏-频率的多项式模型,并利用上述模型对陀螺进行了补偿,分析了补偿结果.实验证明,所述方法能显著提高杯形陀螺的温度性能.%Temperature is one of the most important factors that affect the precision of the cupped gyroscope. For removing or reducing the effect of temperature, the origination of the temperature bias is analyzed, then a method based on the internal signals of the cupped gyro to compensate the temperature bias drift is proposed. After large numbers of temperature experiments, the polynomial models of the bias-temperature, bias-drive voltage and bias-frequency are established, respectively. Then use these models to compensate the temperature bias of the cupped gyro, and analyze the results. The experiments' results proved that this method can improve the temperature-dependent performance of the cupped gyroscope remarkably.
