摘要
在高速电机原理型直接转矩控制(DTC)的基础上提出了改进办法,通过用空间矢量脉宽调制(SVPWM)技术替代原理型DTC中的开关矢量表,既继承了DTC固有的简单且动态性能好的优点,又很大程度上地克服了原理型DTC易产生抖颤的缺点,并通过试验对改进型DTC进行了验证。
Conventional direct torque control （DTC） scheme usually make motorized spindle being quiver because of the switching table. An extension of the DTC scheme is provided based on the conventional way. The main features of the conventional DTC are fully preserved, namely, its simplicity and its excellent dynamics performance. Moreover, the amplitudes of the motorized spindle quiver also have been bated by means of the space-vector modulation （SVPWM） function. Simulation and experimental results are given which confirm the validity of this approach.
