Multiphase Induction Motor Control

This chapter presents a new complex dynamic model of a multiphase induction motor considering an arbitrary number of stator and rotor phases and including the odd order harmonic injection. Starting from the machine equations, the indirect rotor field-oriented control (IRFOC) is extended to the multiphase general case. Finally, some simulation results are presented in the specific case of a five-phase induction motor. The power-oriented graphs (POG) technique is a graphical energy-based technique particularly suitable for modeling dynamic physical systems. The basic structure of a multiphase star-connected induction motor is shown in the chapter. The electrical and mechanical parameters of the motor are listed in a table. All the electrical parameters of the motor have been obtained connecting in series the p polar couples of the motor. This edition first published 2013 © 2013 John Wiley & Sons, Ltd.
