摘　　要：针对超声波电动机自锁能力强、响应速度快的特点,提出了一种基于STM32的超声波电动机直线定位方法。通过对光电编码器产生的信号再次处理,精确控制超声波电动机的旋转角度,进而达到利用超声波电动机进行高精度定位的目的,使直线定位系统的误差进一步减小。实验结果表明,该方法能较好地达到利用超声波电动机进行高精度定位的目的。According to the characteristics of ultrasonic motor which has the self-locking and the advantages of fast response, an ultrasonic motor positioning method based on STM32 was proposed. By processing the signal generated by thephotoelectric encoder again, the rotating angle of ultrasonic motor was accurately control, and the purpose of high precisionpositioning of using the ultrasonic motor was achieved, further reducing the error of the linear positioning system. The experimental results show that this method can achieve the goal of using ultrasonic motor for high precision positioning.
