Estimation of interior-permanent-magnet-synchronous-motor rotor position by analysis of phase-current derivatives
Abstract
This paper describes an algorithm for estimation of IPMSM rotor angular position. The algorithm uses derivatives of motor phase currents resulting from PWM modulation to obtain the rotor position. The presented method is designed for medium- and high-speed range, since it is based on determination of the EMF vector. Calculation of the motor position is performed in every PWM cycle. The standard SV-PWM method is used to determine the sequence of inverter switching during a modulation period. The basis of the algorithm is presented, accompanied by an error analysis. Simulation and laboratory test results are given and discussed.
