基于加速度回路的天线随动系统控制器设计

摘要

为了解决天线随动系统所存在的振颤现象和全数字化实现等问题,介绍了一种基于加速度回路的全数字化天线随动系统控制器,该系统以DSP芯片TMS320F2812为核心控制芯片.采用速率陀螺平台稳定系统、数字PID控制算法和脉宽调制驱动方式,通过引入加速度回路抑制系统的高频振荡,极大地改善了系统的稳定性和动态品质,具有极高的应用价值.%A full digital antenna servo system controller with accelerate circuit was designed to solve shaking phenomenon and realization of full digitization existed in antenna servo system. The system adopted TMS320F2812 DSP as the core control processor, used a stable system scheme of rate gyro platform, digital PID control algorithm and PWM drive mode, introduced high-frequency oscillation of accelerate circuit restrain system, so as to improved the stability and dynamic character. It proves that the system has significant practical value.
