摘　　要：该文对行波超声波电机的运行特性进行了试验研究,指出一般控制方法对行波超声波电机的精密定位可控精度相对较低、转速过快、算法复杂,提出了一种可控精度高、转速低、简单可行的行波超声波电机的控制策略——微步控制方法。通过试验验证该方法可大大提高其精密定位的精度,而且可实现低速、稳定运行,为扩大行波超声波电机的应用范围打下了良好的基础。This paper firstly makes research into the running characters of traveling wave ultrasonic motor（USM）,and points out the disadvantages of relatively low precision,high speed and complex algorithm of traditional control methods;it then discuss an easy,high precision,and low speed control strategy of traveling wave USM!named micro-step control method.Experiments prove that micro-step control method can highly enhance the precision of position,and can make the traveling wave USM run stably in low speed status.Therefore,this method can enlarge the application area of traveling wave USM.
