ABSTRACT

The stability and robustness of the control system for a dual hybrid system's permanent magnet synchronous motor are analysed. Various control techniques, such as current vector control, flux weakening control, PI current control, and SVPWM control, are examined. The motor operates in different modes including initialization mode, normal mode, fault mode, active discharge mode, and power down mode. To ensure occupant safety and prevent damage to vehicle components when facing obstacles like high resistance or steep uphill slopes, motor stall control is implemented. Active short control is defined to avoid feedback of motor current to the battery through the continuous current diode of the IGBT and minimize excessive braking torque generated by the back electromotive force after closing the three-phase bridge arm at high speeds. Finally, successful validation of the motor control design is achieved through real vehicle testing.
