| 摘 要： | 旋转变压器是伺服电机控制系统中的常用位置传感器,但其输出是含有角度量的模拟电压信号,不能直接用于数字化伺服系统。利用旋转变压器信号的相频特性,用STM32微控制器实现同时对多通道旋转变压器信号的数字转换,这种方法解决了传统A/D转换器信号转化速度慢且不能同时转换的难题。

| Abstract: | Rotary transformer is a common sensor element in the servo motor control system,but its output is analog voltage signals containing angle,cannot be directly used in digital servo system. Based on phase frequency characteristics of rotating transformer signals,STM32 microcontroller is used to convert multichannel rotary transformer signals to digital signals at the same time,this method has solved the lowspeed problem and problem of being unable to convert at the same time of traditional A / D converter. |
