基于数字平台罗经的舰载雷达大惯量伺服系统设计

The design of a large inertia servo system of a shipborne radar based on digital platform gyrocompass

介绍了一种在低数据率的数字平台罗经接口下某舰载雷达伺服系统对大惯量稳定平台进行稳定跟踪的设计方法。该伺服系统采用全数字的伺服控制模块作为其位置环的控制核心,利用伺服电机驱动器实现伺服电机速度电流双闭环,组成了一个有良好位置控制性能的数字伺服系统。

In view of the problem of the low-data-rate digital signals from the digital platform gyro- compass of a shipborne radar, a new servo system is designed to steadily track the large inertia stabilizing platform. The fully-digital servo control module is adopted as the control core of its position ring, and the motor drive is used to realize the speed-and-current double closed loop of the servo motor for the servo system. Finally, a digital servo system with the better position control perform- ance is formed.
