N2 - This work focuses on an accurate Extended Kalman Filter (EKF) observer which estimates speed, position, stator flux linkage and torque for interior permanent magnet synchronous motors (IPMSM), over a wide speed range including the very low speed region. The EKF observer is basically a stochastic observer for the recursive optimal state estimation of a non-linear, time-variant, dynamical system like IPMSM in real time by using signals that are corrupted by noise. The EKF has robustness to parameter variations, model inaccuracy and measurement noises. Realistic simulations accounting for the inaccuracy of an actual digital signal processor (DSP) implementation are presented.
