【摘要】：超聲波電機(Ultrasonic motors,簡稱USM)是一種利用壓電陶瓷逆壓電效應(yīng)激發(fā)的超聲振動作為驅(qū)動力,通過定轉(zhuǎn)子間的摩擦力來驅(qū)動轉(zhuǎn)子運動的新型直驅(qū)電機。與傳統(tǒng)的電磁電機相比,它具有低速大轉(zhuǎn)矩、無電磁干擾、動作響應(yīng)快、運行無噪聲、無輸入自鎖等卓越特性,在非連續(xù)運動領(lǐng)域、精密控制領(lǐng)域比傳統(tǒng)的電磁電機性能優(yōu)越得多。在工業(yè)控制系統(tǒng)、汽車專用電器、精密儀器儀表、辦公自動化設(shè)備、智能機器人等領(lǐng)域有廣闊的應(yīng)用前景,近年來倍受科技界和工業(yè)界的重視,成為當(dāng)前機電控制領(lǐng)域的一個研究熱點。本文主要研究基于Zigbee的超聲波電機無線控制技術(shù)。首先本文分析了超聲波電機和Zigbee技術(shù)的特點,對60mm環(huán)形行波超聲波電機進(jìn)行了接觸面的模型仿真。然后,以MC9S12XS128單片機為核心,設(shè)計了超聲波電機的驅(qū)動控制器,并進(jìn)行硬件電路的仿真實驗。以此為基礎(chǔ)再結(jié)合Zigbee技術(shù)構(gòu)建的MESH網(wǎng)絡(luò),以及采用Labview虛擬軟件編寫的上位機監(jiān)控界面,實現(xiàn)對超聲波電機的無線控制,極大地降低了超聲波電機對工作環(huán)境的要求。最后,對搭建的超聲波電機無線控制平臺進(jìn)行了PID速度控制,并給出了相應(yīng)的實驗結(jié)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.
