摘要
简介了超声马达的结构和工作原理,针对超声马达结构特殊、机理复杂的特点,从控制的角度出发,采用系统辨识的方法,建立了行波型超声马达的三种数学模型,实验结果证实了模型的有效性。
In this paper, the structure and the operation principle of ultrasonic motors are introduced firstly. Then several models, as viewed from control, of travelingwave ultrasonic motor including its driver are established by identification method, on account of its special structure and the complicated working principle. Experimental results have verified the validity of the proposed models.
