| Abstract: | A position-sensorless control strategy of a doubly fed induction machine(DFIM)is described.A DFIM sensorless digital control system based on DSP TMS320F2808 is implemented,in which the algorithm needs only measured the stator voltage,the rotor and stator currents,the position and rotor speed can be achieved only with axis transformations,simple multiplication and division operation.The proposed algorithm is easy to design and implement.Experimental results indicate that the proposed method can precisely est... |
