摘要
介绍一种双自由度地面接收天线自动跟踪驱动系统,系统采用单片机实现位置伺服控制,并可与上位 PC 机实现 RS-232 通信,利用混合式步进电动机作为执行元件,经减速机构后驱动天线。介绍了系统工作原理、步进电动机细分控制、位置检测与闭环控制方略,对系统测控结果进行了分析。
A double freedom automatic tracking drive system used in ground receiving antenna is introduced. The system uses microcontroller to realize double free- dom position servo control, and communication with PC through RS-232 interface, and hybrid stepping motor as executing device that drives the measure aerial through decelerator is used. The theorem of system, meticulous control circuit, position measure and close-loop control strategy and data result analysis are given.
