Direct torque control using space vector modulation ( svm - dtc ) scheme is discussed and the detailed designed , including space vector choosing and modulating , to overcome the control difficulties coming with the characteristic of low inductance . comparing with the basic dtc , the simulation results confirm the feasibility and good performance of this strategy . in order to reduce the torque error in dynamic state resulted from the nonlinear relationship between the torque and torque angle , a proportional - plus - integral ( pi ) torque controller with variable proportion is presented to ensure exact and quick control of torque in dynamic state
系统的阐述了永磁同步电机直接转矩控制理论，分析了改进后的svm - dtc控制策略，并具体设计了控制技术的实现方案，包括参考矢量的生成和空间电压矢量调制的方法；为减小电磁转矩与转矩角非线性关系这一因数给电机电磁转矩动态调节造成的误差，本文实现了变比例系数转矩pi调节器的方案，确保了系统稳定性的同时，实现了电磁转矩在动态过程中快速而准确调节。
