Abstract

A general model suitable for the vector control of the unsymmetrical two-phase induction machines is presented in the paper. Both the rotor flux oriented and the stator flux oriented control strategies are analysed and their suitability for low and high-speed operation is discussed. In the mathematical model the machine main and auxiliary winding are represented in the stationary reference frame and the effect of core losses and the main flux path saturation are included. A special technique is used to model different levels of saturation on the two axes of magnetisation. The model can be employed for the accurate simulation of both the steady-state and the transient operation of the unsymmetrical two-phase induction machines
