摘要
介绍了永磁同步电动机实现控制算法的模块化设计。针对永磁交流伺服系统中存在的抑制负载转矩扰动和低速下的实时速度检测问题,采用了基于自适应扰动观测器的统一方法加以解决。实验结果证明了所研究算法的有效性。
This paper presents a permanent-magnet ac servo system based on DSP and FPGA. The vector control has been analyzed and a modular control approach is implemented. Two problems in AC servo system are researched which are load torque ripple and instantaneous speed detection. A unitive method based on adaptive disturbance observer is proposed. The experimental results show the validity of the proposed algorithm in this paper.
