摘　　要：讨论了速率陀螺零位对直升机载导弹飞行控制系统性能的影响,提出了一种针对压电速率陀螺设计的零位校正方案,应用数字滤波器对速率陀螺零位进行跟踪与提取,并根据导弹挂飞工作环境设置判据以保证所提取零位的真实性。该方案的有效性通过了直升机挂飞试验的验证。Influences caused by rate gyro zero position on flight control system of helicopter airborne missile were discussed. A zero-calibration for piezoelectric velocity gyro was proposed, in which digital filter was applied to tracking and picking up the gyro zero position, and an effective threshold was set according to the missile＇s working environment on helicopter to ensure the reliability of zero-position being picked up, The availability of this approach has been proved by helicopter airborne flight experiment.
