摘要
介绍了基于SPWM控制的永磁交流伺服调速系统,在分析永磁同步电动机的数学模型和矢量变换SPWM控制原理的基础上,在MATLAB/SIMULINK环境下建立交流调速系统模型进行仿真。仿真结果表明系统调速平滑、谐波成份小,具有良好的动静态特性。
Based on the analyses of the permanent magnet synchronous motor and vector transform of SPWM control principle, the model of AC speed adjusting system was established and simulated in MATLAB/SIMULINK environment. The system could regulate speed smoothly and the harmonic wave components are small, which has good dynamic and static characteristics.
