Abstract

Electric machines with dual mechanical ports are increasingly investigated in many new industrial applications, such as dual-rotor contra-rotating system in wind power generation. Double-rotor flux-bidirectional-modulation (DR-FBM) machine is one of most promising design, which has an ingenious structure which integrates two separate mechanical ports and two sets of electric ports within one compact machine while eliminating brushes and slip-rings. Accurate position information is very important for the precise control of DR-FBM machine and sensorless position estimation is a very challenging issue to be addressed. In this paper, a dual sliding-mode observer (SMO) based sensorless control strategy is developed and proposed for the control of a DR-FBM machine. The effectiveness of DR-FBM machine design and dual-SMO sensorless control strategy is verified by finite element method (FEM) and Simulink simulations. In this paper, the prototype of the DR-FBM machine is fabricated and the control strategy is implemented on it with a six-phase voltage source inverter. Both the simulational and experimental results agree well with each other, which verify the effectiveness and efficiency of the proposed sensorless control strategy.
