在分析永磁同步电动机的制动过程和矢量控制理论的基础上,提出了基于矢量控制算法来实现永磁同步电动机的回馈制动。在分析永磁同步电动机回馈制动实现的前提条件时,考虑到传统的电流滞环控制方式无法实现电能的回馈,又提出了一种全新的电流滞环控制策略。而后在Matlab/Simulink中搭建了整个系统的数学模型,并从仿真结果验证了基于矢量控制的永磁同步电动机回馈制动的可行性。
This paper proposed a method of in which the vector control was used to achieve regenerative braking of permanent magnet synchronous motors and the precondition of permanent magnet synchronous motor regenerative braking was theoretically analyzed,considering traditional current hysteresis control method cannot achieve regenerative braking.A new current hysteresis control strategy was also put forward.Mathematical model of the entire system was established with the Matlab/Simulink software,simulation results show that the regenerative braking of the permanent magnet synchronous motor based on vector control is feasible.
