| Abstract: | For a brushless double-fed machine, this paper proposes a slip type vector control strategy. Firstly, we derive the state space model in arbitrary rotating mt coordinates. On this basis, the designing method of the slip type vector control strategy is presented. According to the given rotor flux and torque, the given current components and slip of the control machine can be obtained. Then the rotor flux and total torque can be controlled by the flux current component and torque current component of the control machine. Simulation results show that the proposed strategy has excellent tracking performance and adjustment ability, and has robustness to the parameters errors. |
