摘要
在分析SVPWM调制原理的基础上,对一种改进SVPWM的建模方法进行了详细研究.借助于Matlab强大的仿真建模能力,结合异步电动机MRAS矢量控制模型,建立了改进的仿真模型,并将其与SVPWM的一般仿真模型比较.仿真结果验证了改进的SVPWM仿真模型的正确性,与传统SVPWM相比结构简单,逻辑性强,运算量减少.
An improved modelling of SVPWM is researched based on the analysis of the SVPWM. Through the powerful simulink of the Matlab simulation software,a simulation model of improved SVPWM with MRAS vector control of induction motor is established. Simulation and experimental results have verified that the improved SVPWM simulation model is correct,and the improved simulation model has simple structure,strong logic and reduced amount of computation compared with the traditional SVPWM model.
