switch motor meaning in English

转辙电动机

In order to research sinusoidal - and trapezoidal - current compound driven technology , the controller uses variable structure control ( vss ) , by designing switch function s ( x ) , which switches motor between sinusoidal - and trapezoidal - current driven technology , and thus realizes motor ' s excellent control in different range of speed . also we do software simulation using matlab
为了研究方波驱动和正弦波驱动的复合控制，控制器采用变结构控制，通过设计切换函数，使电机在正弦波驱动和方波驱动两种控制模式下切换，实现不同速度段的优良控制特性，并用matlab软件对整个复合驱动系统进行了仿真实验。
