摘　　要：为避免传统模拟电路的缺点,采用单片机ADuC812构建了一种实用四频差动激光陀螺腔长控制系统。系统核心采用PID算法,包括确定工作点、扫模、跳模处理等程序。经反复实验,本系统的稳频精度达10-7量级,能满足应用要求。To avoid the drawbacks of analog circuits, a set of cavity length controlling system for four frequency differential laser gyro based on the ADuC812 is designed. The PID algorithm is adopted in software, including operating point confirming, mode searching and mode jumping program. Experiments show the frequency stabilizing precision of the system can reach 10^-7 degree,which can meet the need of application.
