| titleOfInvention | Position-sensorless model prediction control system and method for permanent magnet synchronous motor for vehicle |
| abstract | The invention relates to a vehicle permanent magnet synchronous motor position sensorless model prediction control system and a method thereof, wherein the system comprises: the maximum torque current ratio controller acquires a stator current reference value; a stator current feedback module: obtaining a stator current feedback value; the position observer module is used for observing the rotating speed and the rotor position angle of the permanent magnet synchronous motor; the current prediction control module is used for carrying out current prediction control according to the stator current reference value, the stator current feedback value, the rotating speed of the permanent magnet synchronous motor and the rotor position and outputting a stator voltage reference value; the rotating high-frequency voltage injection module generates a rotating high-frequency voltage signal and superposes the rotating high-frequency voltage signal with a stator voltage reference value to obtain a control voltage; the SVPWM modulation module: and carrying out SVPWM (space vector pulse width modulation) on the control voltage to obtain an inverter control signal, wherein the inverter is connected with the permanent magnet synchronous motor. Compared with the prior art, the invention can realize the optimization of the current control performance, simplify the hardware of the controller and improve the reliability of the control system. |
