Pei Gao-ke, Gao Jun-li, Tao Di-zhuang, et al. Design of Ultrasonic Motor Driver Based on DSP[J]. 2015, 32(3): 97-101.DOI: 10.3969/j.issn.1007-7162.2015.03.018.
After analyzing the key techniques on the ultrasonic motor (USM) driving
this paper designs USM driver by the pushpull amplifier and parallel matching inductance circuit based on the enhancement pulse width modulator module (EPWM) of TMS320F28027 DSP. And then this design is tested under the computer simulation on the Multisim software platform. According to the characteristics of USM start
a frequency conversion start mode is also configured. Then
the software and hardware joint debugging on the USM driver is implemented which proves effective and satisfactory.
