摘要
半球谐振陀螺作为新型振动陀螺,具有长寿命、长稳定期、高精度等优点,能显著提高惯性系统的性能。讨论了半球谐振陀螺的特点,分析了其误差模型,研究了半球谐振陀螺在平台惯性系统的应用技术和方法,重点介绍了基于半球谐振陀螺的平台稳定回路、框架归零回路和调平锁定回路设计,并通过试验样机进行了试验验证。
As one of newly-type vibrating gyro with long life-time,long stable-period and high accuracy,Hemispherical Resonator Gyroscope(HRG) can upgrade greatly the performance of the platform inertial system.The characteristics of HRG are discussed,its error models are analysed and the technologies and methods of the platform inertial system based HGR are studied,especial stability loop,gimbal-zeroing loop and leveling-locking loop.Finally the calibration experiment and analyses are carried out.
