摘要
天线在载体运动过程中会产生动态指向偏差,影响探测效果。稳定平台是用来稳定天线指向的一种自动调节装置。介绍了一种天线稳定平台控制系统的设计、原理及实验结果。它主要由速度控制,位置控制两部分电路组成,其中使用光纤陀螺仪测定平台实时姿态,通过PC／104嵌入式工控机分析运算,经光电编码器与交流伺服电机组合驱动平台以实现天线指向的稳定。实验结果表明该稳定平台控制系统能够满足对天线指向稳定的控制要求。
The movement of carrier causes direction change of its antenna, and makes the antenna working incorrectly. The stable platform is equipment which can stabilize the direction of antenna. This paper describes a kind of design and principle of a stable antenna platform. It mainly consists of a speed control circuit and a position control circuit. The velocities of the platform are detected by three fiber gyros, and the real-time positions of platform are detected by three encoders. A PC/104 computer processes the velocity and position information and controls the antenna. It can work stably with the control system of platform. is proved by the experiment results that the antenna
