This paper presents improvements of the stator flux estimation for a variable structure direct torque controlled (DTC) interior permanent magnet (IPM) synchronous motor drive. A variable structure observer is proposed to estimate the stator flux linkage based on the IPM motor current model. Compared to open-loop estimator, the observer improves the performance of the IPM motor drive. The experimental results demonstrate that the proposed observer is able to deliver more accurate estimation than… CONTINUE READING
