中文摘要	当永磁同步电机在转子磁场定向控制方法下运行时,由于电机齿槽以及逆变器死区效应等非理想因素的影响,d、q轴电流中会包含谐波。为了抑制电流谐波,该文采用在电流控制环上并联谐振调节器的方法对特定的谐波进行抑制。谐振调节器在给定的谐振频率下有无穷大的增益,因此可以对该频率的谐波进行完全抑制,但是当输入为阶跃信号时,电流响应会出现超调。为了消除超调,同时提高电流的动态响应速度,采用一种前馈控制方法,同时考虑数字控制延时的影响,达到了电流响应没有超调,快速跟踪的效果。为验证该文提出的方法,进行了仿真分析,并在1.25 kW永磁同步电机实验平台进行了实验,验证了该文方法对电流谐波抑制及动态响应速度的提升作用。; When permanent magnet synchronous motor(PMSM) is controlled by field oriented control method, dq-axes current will contain harmonics due to non-ideal factors including slot effect of the motor, dead-time effect of the inverter, etc. To suppress the current harmonics, the resonant controllers are used in this paper by adding to the current control loop. The gain of resonant controller at the given resonant frequency is infinite, so it can suppress the harmonic totally at this frequency, however, when the input happens to be a step signal, the overshoot will occur in the current response. To eliminate the overshoot, and also to improve the dynamic response of the current, a command feed-forward compensation method is used in this paper, meanwhile the effects of the digital control delay are considered. Current response without overshoot is achieved with fast current response. To demonstrate the method proposed in this paper, simulation study is done, experiments are also finished on a built 1.25 kW PMSM platform, the effectiveness of the proposed method including the suppression of current harmonics and the improvement of the dynamic response is verified.
