摘要 分析了基于空间矢量调制(SVM)的异步电机直接转矩控制算法的原理,并加以改进,引入磁链观测全速度模型,使磁链观测更加准确。通过Matlab/Simulink仿真研究,验证了算法的有效性。在此基础上实际应用于基于VxW orks嵌入式系统的变频调速系统平台,取得了良好的控制效果,证明此算法在工程中具有很好的应用前景。 A algorithm of direct torque control(DTC)of induction motor drives based on space vector modulation(SVM)was analyzed deeply and improved,The flux full speed model was adopted,which made the flux observation more accurate.Though the simulation research,its effectiveness was proved.Then,the algorithm was applied on a system which base on VxWorks embedded OS,though actual operation,a good result was achieved,which can indicate the algorithm has a good application prospects in project.
