hybrid simulation system meaning in Chinese

混合模拟系统

In this thesis the author made a study of asynchronous motor model , designed a hybrid simulation system of dtc and analyzed the characteristics of the dtc system and the existing problems detailedly . due to the large torque ripple of induction motor in dtc system , especially in low speed , this thesis proposed a discrete time space vector modulation and designed a sliding - mode torque and flux controllers based on sliding - mode theory to overcome this drawback
由于直接转矩控制存在的不足之处主要在于转矩脉动，特别是在低速运行时这种情况更加突出，针对该问题，本文提出了一种离散时间空间矢量合成法来改善转矩脉动，并且引入滑模理论，设计了一种滑模转矩和磁链控制器来克服这一缺点。
