In this paper, a fiveleg inverter is proposed as a control object, and a cooperative control strategy based on model predictive control strategy is proposed. Compared with the traditional algorithm, the new algorithm adds torque synchronization Strategy to ensure the output power balance of the two motors, while the crosscoupling control thinking into the fiveleg two motor control system speed outer loop controller to improve the two motors do not match the parameters of the speed synchronization performance. Simulation results show that the new algorithm can effectively improve the synchronization performance of the motor speed and torque of the two motor systems under the precondition of keeping the torque control speed of the model predictive control algorithm higher than the traditional control strategy, and has certain application value.
