Abstract

Due to the advantages of high torque density and compact mechanical structure, brushless dual-mechanical-port dual-electrical-port (BLDD) permanent magnet (PM) machine has become a promising alternative in series-parallel hybrid electrical vehicles (HEVs). However, two sets of windings in the same core may also result in flux cross coupling, which deteriorate control performance. Through special design of the magnetic circuit, the two sets of windings in the stator side are decoupled. In this paper, the mathematical model of the BLDD-PM machine is analyzed first. Then, based on the energy management system and the model of the machine, the decoupled vector control algorithm for the outer and inner rotor is developed. Next, common operation states under city road condition for hybrid vehicles have been summarized. According to the operation state of HEV, the power flow analysis in the BLDD-PM machine system has been done. To validate the analysis results, experimental test under different operation condition has been conducted. Test results show good control performance of the BLDD-PM prototype and verify the correctness of analysis.
