The contributions done are as follows : according to the mathematical model of doubly fed motor and the theory of vector control, a unit power factor of rotor control scheme is proposed. in the doubly fed adjustment system, in order to control magnetic torque of motor this scheme is designed by controlling the reverse direction between rotor voltage and current to keep the vertical direction between rotor current and flux. it is known from theoretical analysis that for partly decoupling this scheme is only effective under sub - synchronization speed, but not control the system and obtain steady state since speed adjustment system ca n ' t adjust the magnitude of rotor flux under sup - synchronization
而傳統的無速度傳感器雙饋調速矢量控制系統，由於採用磁鏈定向方法，在同步速附近存在較大的工作死區，針對上述問題，本文做了如下的研究工作：本文從雙饋電機的數學模型出發，根據矢量控制的基本原理，提出了一種轉子側功率因數為1的雙饋電機矢量控制方案的設想，即在雙饋調速時採用轉子電流定向的方法，並控制外加轉子電壓與轉子電流始終反相，以保持了轉子電流與轉子磁鏈矢量垂直，通過控制轉子電流的大小來達到控制電機電磁轉矩的要求。 -
