摘要
本文以应用于某轻型战场侦察雷达的伺服控制系统为例,介绍了一种采用DSP芯片TMS320F28335为控制核心,辅以执行元件步进电机,反馈元件增量式光电编码器来完成伺服速度、位置控制,使雷达天线具备圆扫、扇扫和凝视功能。提出一种天线过零位角度换算方法,并对天线扇扫和凝视的运行轨迹作了智能优化处理。
In this paper, a serw〉 control system for a light battlefieht reconnaissance radar is taken as an example which using a DSP chip TMS320F28335 as the control core, supplemented by the implementation of component stepper motor, feedback element of incremental photoelectric encoder to complete the servo speed and position control, so that the radar antenna with a round sweep, fan sweep and gaze function. Additionally, a method of antenna zero crossing angle conversion is presented, and an intelligent trajecto~ of the antenna scanning and gazing is optimized.
