摘要
本文在分析激光陀螺高压稳流电源工作原理的基础上,利用DSP实现数字PID控制算法,对激光陀螺两臂放电电流进行闭环稳定控制,实现了高精度的激光陀螺数字稳流电源。经过长时间的室温测试实验和高低温测试实验,其单臂稳定度已优于1×10-4,两臂电流差值的稳定度也已高达1×10-5。结果表明其性能已经达到了现有激光陀螺模拟稳流电源的性能。激光陀螺高精度数字稳流电源的实现,对未来激光陀螺工作电路实现高度的数字化、集成化和一体化有十分重要的现实意义。
Baaed on analyzing the principle of Laser Gyro high- voltage power supply, using DSP to realize PID algorithm for controlling the current of tow arras stability, the high - precision digital current control power supply system for Laser Gym is accomplished. Though long time tests under room temperature and Hi - Lo temperature conditions, the turret stability of any arm can reach 1 × 10^-4, the current difference stability of the two arms even can reach 1 × 10^-5.The test results show that the digital current control system is good enough to compare with the analog current control power supply system in the performance. The realization of this digital current control system is very important to accelerate the digitalization , integration and all - in - one for all the Laser Gyro wonk circuits.
