摘　　要：速率指标是评价速率转台和其它具有速率功能的惯导测试设备的重要指标之一。针对惯性技术测试设备速率指标的测试方法无法反映转台运行中瞬时速率的问题,分析了转台瞬时速率波动的原因,在转台速率环引入巴特沃斯低通滤波器,通过MATLAB仿真分析和转台速率运行曲线,进一步说明了此滤波器的有效性。The porrameter of rate is very important to evaluate the rate turntable and other inertial navigation test devices with rate function. In view of the inertial testing equipment,the rate test method can＇t reflect the instantaneous angular rate in the operation of turntable.Based on the analysis of the turntable rate fluctuation,butterworth low-pass filter was used in the turntable rate ring. The effectiveness of the filter was demonstrated through MATLAB simulation analysis and table velocity curve drawing.
