摘要：为了提高双馈风力发电系统的控制性能，本文提出了一种基于反推算法的双馈风力发电系统直接功率控制策略。首先建立了基于定子磁链定向控制的双馈异步发电机数学模型，然后将反推控制与直接功率结合，从实现功率跟踪的目标着手，进行反推控制器的设计。在Matlab/Simulink环境下对该系统进行了仿真。仿真结果表明，所设计的控制器可以实现对风力发电系统有功功率和无功功率的跟踪，且具有良好的动、静态特性和鲁棒性。

Abstract: Torque ripple of the servo motor performance testing, servo motor installed on the test bench, the precision of the structure and installation of the concentricity deviation will lead to additional torque, remove additional torque is needed to get the actual values of torque ripple servo motor. This paper introduced the method based on timefrequency transform applied to remove the additional torque, and the use of LabVIEW software design implementation, through simulation and applied to the actual test system software, satisfactory results have been achieved.
Key words: servo motor; torque ripple; additional torque; test method |
