Abstract
Basic principle of brushless doubly-fed machine were introduced, and its d-q mathematical model was studied. The dynamic simulation of brushless doubly-fed machine under open-loop was realized on Matlab/Simulink platform by use of constant V/F control strategy, while open-loop speed regulation experiment of brushless doubly-fed machine was completed on the experimental platform based on two-three-level inverter. Simulation and experimental results verified operation mechanism and good dynamic characteristics of brushless doubly-fed machine.
