The brushless doubly-fed machine (BDFM) is based on the technic of fieldoriented control and the performance of its adjustable-speed drive can ultimately meet the need of the operation.
Based on the theory of vector control and automatic control system, the vector control system of current model for doubly-fed asynchronous machine with field-oriented rotor was established.
根据矢量控制理论和自动控制原理,建立了转子磁链定向的双馈异步电动机电流模型矢量控制系统。
