摘要
在深入分析超声波电机(USM)驱动关键技术的基础上,基于TMS320F28027 DSP的增强性脉宽调制器模块(EPWM),采用推挽式驱动放大和并联匹配电感电路,设计USM驱动器,并通过Multisim软件平台进行计算机仿真.针对USM的启动特点,设计一种变频启动方式,实现USM驱动器的软硬件联合调试.实际应用效果良好.
After analyzing the key techniques on the ultrasonic motor （ USM） driving, this paper designs USM driver by the push-pull 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.
