基于模型预测的双电机转速同步控制研究

Research on Dual Motor Speed Synchronous Control Based on Model Prediction

永磁同步电机作为工业生产的核心部件在各个领域发挥着重要作用,但传统的生产过程常用单电机驱动实现控制,这种控制方式有电机输出转矩较小,行程较短等缺点。当较大的传动功率或者对位置控制性能要求较高时,这种控制方式无法达到要求。针对单电机驱动不足,设计了一个双机驱动系统,主要通过对永磁同步电机驱动控制策略及多电机同步控制方式进行研究,有效保证了能满足更大推力更长行程的实际应用需求。针对双电机转速难以同步的问题,本文提出了基于模型预测的双电机同转速控制策略,并在仿真模型中验证其性能。

Permanent magnet synchronous motors,as the core components of industrial production,play an important role in various fields.However,traditional production processes often use single motor drive to achieve control,which has disadvantages such as small motor output torque and short stroke.This control method cannot meet the requirements when the transmission power is large or the position control performance is high.Aiming at the shortage of single motor drive,a dual-motor drive system was designed.The permanent magnet synchronous motor drive control strategy and multi-motor synchronous control method were studied,which effectively ensured the practical application requirements of larger thrust and longer stroke.In response to the problem of difficult synchronization of dual motor speeds,this paper proposed a model prediction based dual motor speed control strategy,and verified its performance in simulation models.
