摘要

通过对感应电机极数的电子控制,极相调制可以在高动态应用中提供性能优势。建立了适用的动力学模型,并通过有限元分析进行了验证。所提出的模型可以描述具有任意数量的电输入和极数配置的机器。多相矢量空间分解的可用自由度用于为每个可用的极数开发解耦的能量转换子空间,从而允许直接应用常规控制技术。给出了利用磁场定向控制技术实现2极/6极平滑过渡的仿真结果。

A dynamic pole-phase modulation induction machine model
Pole-phase modulation can provide performance benefits in highly dynamic applications through the electronic control of induction machine pole count. An applicable dynamic model is developed, and verified using finite element analysis. The proposed model can describe machines with an arbitrary number of electrical inputs and pole count configurations. The available degrees of freedom in polyphase vector space decomposition are used to develop decoupled energy conversion subspaces for each available pole count, allowing conventional control techniques to be directly applied. Simulation results for a smooth 2-pole/6-pole transition using field-oriented control techniques are provided.
