In this paper, a Square root Cubature Kalman filter (SCKF) is applied for speed and position estimation in the control of Interior Permanent Magnet Synchronous Motor (IPMSM). Cubature Kalman filter avoids the linearization errors prevailing in the Extended Kalman filter algorithm, and is much easier to tune than the Unscented Kalman filter. The square root version of the Cubature Kalman filter gives...
This paper aims at the following control schemes of the IPM-SM drive, (i) A closed-loop direct torque control of an IPM-SM for variable speed drive with speed/position sensor, (ii) A speed and position sensor-less direct torque control scheme of the IPM-SM drive. To achieve closed loop control of torque and stator flux linkage, two PI controllers has been used; whereas to generate reference voltage...
