摘要
介绍了自整角机位置角信号测量的基本原理,分析了反正切法计算位置角的基本方法,并将TMS320LF2407应用到自整角机轴角数字转换中。为了提高采样精度,采用了过采样技术,并给出了过采样技术的关键实现步骤。应用表明,该系统具有测量精度高、测量速度快、硬件成本低的特点。
A basic way of measuring the position angle signal for synchro was introduced. In this paper digital method of position signal based on TMS320LF2407 and software design were introduced. To improve the performance of shaft angle digital conversion, over sample technique was applied. Such kind of system had the characteristics of high measuring precision, high measuring speed and low hardware cost.
