摘要
以4台永磁同步电机组成的机车牵引系统为对象,提出了一种基于滑模控制的机车多电机协调控制策略,设计了总牵引力矩恒定的多电机协调控制框架,基于永磁同步电机数学模型设计了滑模控制器,通过仿真验证了所提方法的有效性。
Through taking locomotive traction system composed by 4 permanent magnet synchronous motors as an example,the study proposes the multi-motor coordinated control strategy of locomotive based on sliding mode control,and designs the framework of multi-motor coordinated control of constant total traction torque.Based on permanent magnet synchronous motor mathematics mode,sliding mode controller is designed.Through emulation,the effectiveness of methods is proved.
