对于牵引驱动装置，过调制和六阶区域的操作对于增加扭矩-速度范围和驱动装置的效率至关重要。无差拍磁通控制（DBFC）显示出上级的动态性能相比，在这些地区的电流矢量控制器。本文提出了一种DBFC的过调制策略。这种技术，称为最小磁通相位误差（MFPE），允许从线性到六步区域的平滑过渡。因此，调制指数的突变被防止，这导致更平滑的瞬态和更接近最大转矩每安培（MTPA）线的操作。DBFC可以与DB-DTFC（无差拍直接转矩和磁通控制）相结合，以确保在整个转矩-速度范围内的可控性。本文给出了完整的控制策略。300 kW IPMSM硬件在环（HiL）测试台的结果验证了该策略。文中还讨论了该方法的使用注意事项。
For traction drives, the operation in the overmodulation and six-step regions is crucial to increase the torque-speed range and the drive’s efficiency. Deadbeat flux-control (DBFC) shows superior dynamic performance as compared to current-vector-controllers in these regions. In this paper, an overmodulation strategy for DBFC is presented. This technique, named minimum flux-phase error (MFPE), permits a smooth transition from the linear to the six-step regions. Consequently, abrupt changes of the modulation index are prevented which results in smoother transients and a closer operation to the maximum-torque-per-ampere (MTPA) line. DBFC can be combined with DB-DTFC (deadbeat direct torque and flux control) to ensure controllability throughout the entire torque-speed range. The complete control strategy is shown in this paper. Results from a 300kW IPMSM hardware-in-the-loop (HiL) testbench are shown to validate the strategy. Challenging caveats of the method are also discussed.
