摘　　要：针对无刷双馈电机标量控制动态性能差,以及常规直接转矩滞环控制不可避免地产生转矩脉动等问题,提出了基于SVPWM的无刷双馈电机直接转矩控制策略,可获得较为理想的磁链轨迹圆,有效减小转矩脉动,显著提高系统的动态性能及鲁棒性。通过仿真技术对所建模型及控制策略其进行了定量及定性说明。To improve the poor dynamic performance of the scalar control and to suppress large torque ripple of the conventional direct torque control,a direct torque control method for brushless doubly-fed machine based on SVPWM strategy was proposed,which can obtain ideal flux trajectory,effectively reduce the torque ripple,and significantly improve the system dynamic performance and robustness.The model and control strategy was described quantitatively and qualitatively through simulation tech-nology.
