Vector control of permanent-magnet synchronous motors

Schemes and algorithms are considered for vector control of a permanent-magnet synchronous motor by adjusting the stator-field vector magnitude and its angular misalignment relative to the rotor-field vector. The proposed algorithms provide a very varied view of motor mechanical characteristics, demonstrate low sensitivity to the dispersion of engine parameters, use a relatively small amount of computational procedures, and make it possible to implement quite easily a variety of static and dynamic drive operating regimes, including the modes of direct-current control, start, reverse, and others. Simulation results of the drive operation in static and dynamic regimes are given. © 2013 Allerton Press, Inc.
