Motor active response hybrid gearbox mode switching oscillation suppression method based on MPC

The invention discloses a motor active response hybrid transmission mode switching oscillation suppression method based on MPC. The method is suitable for rapid following of the rotating speed of a motor of a hybrid electric vehicle and rapid power compensation. An active response oscillation suppressor is established, rapid response of motor rotating speed following is achieved through an MPC control strategy, a prediction control module and a torque compensation module in the oscillation suppressor are matched with each other to finally output a set of reference voltage to a modulator, and oscillation during mode switching of the hybrid electric vehicle is mainly caused by the fact that a clutch friction disc has the relative speed. The motor rotating speed is actively responded to the clutch driving disc rotating speed, so that the meshing process of the clutch is rapid and stable, and system oscillation caused when the motor is switched in is reduced. The torque compensation module is used for achieving r
