摘　　要：为了解决传统的内置式永磁同步电机弱磁控制系统在高加减速、突加负载过程中响应速度慢、转矩波动大的问题,首先,在分析传统弱磁控制策略的基础上,针对内置式永磁同步电机强耦合的情况,将前馈电压补偿引入到弱磁控制中,实现了一种改进型的弱磁控制策略。其次,在MATLAB中建立带有前馈电压补偿环节的弱磁控制系统模型。最后,对控制系统进行了仿真,仿真结果表明改进后的弱磁控制策略,响应速度快、转矩波动小,提升了系统的性能,对车用内置式永磁同步电机的控制有一定的借鉴意义。In order to solve the traditional weak magnetic built-in permanent magnet synchronous motor control system in the process of higher deceleration,and load response speed slow,the problem of large torque ripple,,first of all on the basis of analyzing the traditional weak magnetic control strategy,for the strong coupling of interior permanent magnet synchronous motor,introducing feedforward voltage compensation to the weak magnetic control,implements a modified weak magnetic control strategy.Secondly,a weak magnetic control system model with feedforward voltage compensation is established in MATLAB.Finally,the simulation results of the control system show that the improved weak-magnetic control strategy improves the performance of the system which can be used as a reference for the control of the built-in permanent magnet synchronous motor.
