摘　　要：电机性能测试的离散数据中包含各种扰,必须对测试数据进行数字处理。文中用计算编程采集光电编码器脉冲值,并采用曲线拟合、数字滤波的方法对所测信号进行处理,得出电机运行特性曲线,为进一步改进超声波电机运行特性和提高控制的性能奠定基础。Analysing the speed of a motor is one of the measures which analyses a motor.But these tested data include all kinds of disturbance.So we must process these data before we use them.In this paper,a program has been designed to receive the data from the photoelectric encoder.Then characters of USM can be taken from these data by using curve fitting and digital filter.This makes the foundation for further improving the running performance of motors and the development of USM controller.
