Title: Control of a Permanent Magnet Synchronous Motor with Non-Sinusoidal Flux Density Distribution
Authors: Wallmark, Oskar
Abstract: This thesis discusses various aspects of controlling a permanent magnet synchronous machine with a non-sinusoidal rotor flux density distribution. The transient model of the machine in the rotor oriented dq-frame is derived, including the non-sinusoidal effects. The design of current and speed controllers is also discussed. The current controller is implemented in a permanent magnet machine, intended for hybrid electric vehicle applications, yielding good results. An algoritm to estimate the rotor position, based on high frequency signal injection and a non linear observer, is also implemented with good results. The flux linkage harmonics are measured and the predicted torque and current ripple are verified by measurements.
