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 deals with the investigation of the Extended Kalman Filter (EKF) for sensorless indirect vector control of an induction motor. The prime focus is low speed operation, when the EKF somewhat presents erroneous results. The effectiveness of the EKF as a speed estimator under machine parameter variations - change in stator resistance, rotor resistance is assessed. Furthermore, the effect of...
This paper aims to develop an innovative direct torque control (DTC) for an induction motor (IM) drive based on model prediction (MP). An effective methodology for the optimum selection of weighting factor is proposed, based on the evaluation of ripple behavior. A sensorless speed estimation technique utilizing the predictive nature of proposed MP DTC is adopted. Firstly, the paper introduces a detailed...
