This report presents an algorithm for reference current calculation to minimize losses in electric vehicles with PMSM. The algorithm calculates the current set points explicitly through analytical expressions depending on the requested torque, the speed of the drive and the available DC voltage. The required machine parameters have been gathered from(More)
This report presents an extension of the Field Oriented Control technique to suppress the 5th and the 7th current harmonics of an IPMSM. The influence of the current harmonics on the fundamental control loop is analyzed and a proposition for their identification is given. Two additional control loops - in parallel with the fundamental control loop-have been(More)
