摘要
提出全数字化激光陀螺控制方案,并实现了全数字控制的激光陀螺——数字陀螺。对比分析了正在使用的模拟控制激光陀螺和数字激光陀螺原理及结构,介绍了数字陀螺的优点和关键技术,给出了抖动驱动为脉宽调制方式实现的波形图和数字陀螺图形化测试数据。实验结果表明,数字陀螺符合激光陀螺发展方向,提高了调试和生产效率,简化了对导航系统的设计和调试要求。
The control scheme of all-digital laser gyro is presented, and the laser gyro of the full digital control, digital ring laser gyro, is implemented. The principle and structure between the analog laser gyro and digital laser gyro are compared, and the advantages and key technologies of digital gyro are described in detail. In particular, jitter-driven pulse-width modulation waveform and graphical test data of the digital gyro is given. It is proved that the digital gyro direction of development in line with the ring laser gyro, improves debugging and production efficiency, and simplifies the requirements for navigation systems.
