Research on Resistance Identification System Based on Speed-Less Senso
Abstract：For permanent magnet synchronous motor, the performance is extremely sensitive to inside and outside disturbances, especially the changes of the stator resistance. A novel adaptive control scheme for stator resistance is proposed in order to improve the system robustness. On the premise of the motor parameters, the stator resistance is identified as unknown parameters and establishes resistance adaptive observer based on the stator current and rotor flux. In the same simulation conditions, the identification between introduction of resistance and not in the direct torque control system, the results prove that the design of adaptive control method can effectively improve the system robustness.
