摘　　要：永磁同步电机在运行时,输出电流的谐波成分对控制的的精确程度造成很大影响,针对这一问题,提出了在永磁同步电机DSP控制器中对反馈电流进行软件滤波。与传统的硬件滤波相比,软件滤波具有结构简单,不增加额外设备等优点。滤波器选用自适应FIR滤波器算法,并对系统进行了仿真,实验,证明了软件滤波的可行性。在实验中,系统反馈电流有了明显的优化,系统的稳定性有了明显提高。证明了在伺服电机控制中自适应滤波的可行性和有效性。The paper analysis of the reasons for permanent magnet synchronous motor generates, composition and its impact on the whole system, presented in permanent magnet synchronous motor controller DSP feedback current filtering software. Compared with traditional hardware filtering, filtering software has a simple structure, no additional equipment and so on. Mature FIR filter selection filter algorithm and system simulation, experiments prove the feasibility of filtering software. In the experiment, the current feedback system has been significantly optimized stability of the system has been significantly improved. It demonstrates the feasibility and effectiveness of the servo motor control filtering software.
