Simulation and Analysis of GMA Driver Waveform Based on Multisim

在研究超磁致伸缩作动器(GMA)等效电路模型的基础上,针对GMA等效电路的特点以及GMA工作性能的要求,利用模拟电路的方法设计了一种SPWM电压波形,用于驱动GMA响应。采用Multisim仿真软件对驱动波形进行仿真分析,并与方波驱动方式进行比较。仿真结果表明,所设计的SPWM驱动波形可以提高GMA的响应速度,改善GMA的动态性能。

A SPWM voltage waveform is designed by using the analog circuit method,which is used to drive the GMA re- sponse.The driving waveform is simulated and analyzed by Multisim simulation software and compared with the square wave driving method.The simulation results show that the designed SPWM driving waveform can improve the response speed of GMA and improve the dynamic performance of GMA.
