摘要
阐述了矢量控制方法的基本原理,推导了三相交流异步电动机的数学模型.结合SPWM和矢量控制方法,采用模块式设计方法和结构化设计在Matlab/Simulink平台上对三相异步电机进行了建模和仿真研究分析.结果表明该系统具有响应速度快、稳态静差小和抗负载扰动能力强的优点,为矢量控制技术在电力传动领域的工程实际应用提供了技术支持.
The basic principles of vector control method are elaborated,and the mathematical model of three-phase AC induction motor is deduced. Combined with SPWM and vector control methods,three-phase induction motor modelling and simulation analysis are completed in Matlab/Simulink platform with modular and structure design method. The results show that the system has advantages of high response capability,little steady static error,strong anti-load disturbance. The study provides technical support for practical engineering application of vector control technology in the field of electric power transmission.
