Parametric Design and Robust Control Strategy for HEV Based on Permanent Magnet Electrical Variable Transmission

摘要

In this study, Permanent Magnet-Dual Mechanical Ports (PM-DMP) machine is used as an Electrical Variable Transmission (EVT), instead the Toyota Hybrid System (THS) transmission, in Hybrid Electric Vehicle (HEV). Decreasing and exploiting the power ratings of the power plants in the HEV system are the most efficient factors for increasing the economy and efficiency of the system. These goals are achieved through three tandem procedures: the first is focusing on the detailed calculations of the power ratings for the PMSM-EVT machines. These calculations are mainly based on the deeply analysis of the function of each plant at steady and dynamic states. The second is the robust vector control of the two PMSMs with the field weakening strategy. The third is developing a robust global power management control strategy to realize the power splitting for the full hybrids. The integration of HEV components including their dynamic models and controllers has been implemented by Energetic Macroscopic Representation (EMR) simulation tool. The goals are validated by the simulation results with two different driving cycles; and from the interim analytical calculations and from analyzing the simulation results, the rated and maximum specifications of the PMSMEVT have been defined. Finally, the results are validated by comparing to the practical data of the Toyota Prius HEV. The results show that the power ratings of the electrical machines are saved more than that of Prius machines. Also, the system is driven at harder burden loads than that of Prius with perfect drivability.
