摘要
介绍了一种步进电机控制自整角机生成正弦信号的方法。通过上位机软件将标准正弦信号离散化,转化成能反应正弦变化规律的定时器溢出率数据,单片机用接收的溢出率数据控制步进电机按正弦规律转动,步进电机通过机械传动器带动自整角机转子转动,生成正弦测试信号。测试结果显示,该方法可满足设计要求,并能对输入正弦信号的各参数进行随意修改。
This article introduces a method for the generation of the sinusoid for control by stepping motor. In order to generate the sinusoid for testing control, the normal sinusoid is changed into time data of the timer by soft-ware. According to the data of the timer, the singlechip turns the electromotor by the law of sinusoid. The parame-ters of sinusoid control signal are optional.
