摘要
激光陀螺作为捷联惯导系统中的主要器件之一，它的性能对惯导系统的整体性能有着很大的影响。将单片机，DSP应用于激光陀螺控制电路设计当中，虽然可以实现激光陀螺控制电路的数字化，但由于其顺序执行指令的特性，必然造成组成惯导系统的三个激光陀螺的信号控制是串行的，对于实时性要求不高的信息，串行控制是最经济、简单和可靠的实现方案，但是对于实时性要求很高或者必须采用并行处理的环节就只有采用增加微处理器的方案为了解决激光陀螺并行控制的问题，提出了一种可以在一块FPGA芯片上对激光陀螺进行数字化并行机械抖动控制和数字化并行稳频控制的合理方案，并进行了试验验证，达到了预期目的。
Ring Laser Gyroscope （RLG） as one of main devices has a great impact on the performance of strap-down inertial navigation system （SINS）. Microcontroller used in the design of the RLG control circuit can achieve RLG control circuit of digitized, but due to the characteristics of its order execution, it will inevitably lead to the signal control of three RLG composed of SINS are serial. For the less demanding real-time system, serial control is the most economical, simple and reliable implementations, but for demanding real-time or parallel processing system must be part of only using the program to increase microprocessor. In order to solve the problem of RLG Parallel Control proposed a program to adopt FPGA technologies for digital bias and frequency stabilization. Finally, through the experimental proves the correctness of the program
