【摘要】：超声波电机(Ultrasonic motors,简称USM)是一种利用压电陶瓷逆压电效应激发的超声振动作为驱动力,通过定转子间的摩擦力来驱动转子运动的新型直驱电机。与传统的电磁电机相比,它具有低速大转矩、无电磁干扰、动作响应快、运行无噪声、无输入自锁等卓越特性,在非连续运动领域、精密控制领域比传统的电磁电机性能优越得多。在工业控制系统、汽车专用电器、精密仪器仪表、办公自动化设备、智能机器人等领域有广阔的应用前景,近年来倍受科技界和工业界的重视,成为当前机电控制领域的一个研究热点。本文主要研究基于Zigbee的超声波电机无线控制技术。首先本文分析了超声波电机和Zigbee技术的特点,对60mm环形行波超声波电机进行了接触面的模型仿真。然后,以MC9S12XS128单片机为核心,设计了超声波电机的驱动控制器,并进行硬件电路的仿真实验。以此为基础再结合Zigbee技术构建的MESH网络,以及采用Labview虚拟软件编写的上位机监控界面,实现对超声波电机的无线控制,极大地降低了超声波电机对工作环境的要求。最后,对搭建的超声波电机无线控制平台进行了PID速度控制,并给出了相应的实验结果。
[Abstract]:Ultrasonic motor (USM) is a new type of direct drive motor, which is driven by the ultrasonic vibration excited by the inverse piezoelectric effect of piezoelectric ceramics and driven by friction between stator and rotor. Compared with the traditional electromagnetic motor, it has the advantages of low speed and large torque, no electromagnetic interference, fast action response, no noise running, no input self-locking and so on, in the field of discontinuous motion. The precision control field is much better than the traditional electromagnetic motor performance. It has a wide application prospect in the fields of industrial control system, automobile special appliance, precision instrument, office automation equipment, intelligent robot and so on. In recent years, it has been paid more attention to by science and technology and industry. It has become a research hotspot in the field of electromechanical control. This paper mainly studies the wireless control technology of ultrasonic motor based on Zigbee. Firstly, the characteristics of ultrasonic motor and Zigbee technology are analyzed, and the contact surface model of 60mm ring traveling wave ultrasonic motor is simulated. Then, the driving controller of ultrasonic motor is designed with MC9S12XS128 microcontroller as the core, and the simulation experiment of hardware circuit is carried out. On the basis of this, the MESH network based on Zigbee technology and the monitor interface of upper computer written by Labview virtual software are used to realize the wireless control of ultrasonic motor, which greatly reduces the requirement of working environment for ultrasonic motor. Finally, the PID speed control of the wireless control platform of ultrasonic motor is carried out, and the corresponding experimental results are given.
