The Control Technologies of PMSM for FAW-TMH System

摘要

In this paper, PMSM (permanent magnet synchronous motor) control technologies combined with HEV (Hybrid Electric Vehicle) application features are developed, which aim at FAW-TMH (Twin Motor Hybrid) system for B70HEV. The technologies are based on FOC (Field Oriented Control) theory and include multiple advanced control functions such as MTPA (Maximum Torque per Amperes) control with decoupling and anti-windup PI controller, PTB (Peak Torque Boost) control, high voltage utilization PWM modulation, deadtime compensation, DTC and map based deep field weakening control and so on. Those control technologies can meet the hybrid electric vehicle's performance requirement under different working conditions. What's more, the proposed deadtime compensation, DTC and map based field weakening control technologies are new in the e-motor controls field. Bench test and road test indicate that the developed PMSM control strategy meets the performance and reliability requirements of B70HEV.
