文档介绍:异步电动机转差频率间接矢量控制matlab仿真
摘要
本文基于 MATLAB 对异步电动机转差频率控制调速系统进行仿真研究。首先分析了异步电动机转差频率控制技术的主要控制方法、基本组成与工作原理。之后对异步电机的动态模型做了分析,进一步介绍了异步电机的坐标变换,对异步电机转差频率矢量控制系统的基本原理进行了阐述,通过仿真工作,证明了其可行性。最后,通过对仿真结果进行分析,归纳出如下结论:单纯的转差频率控制带载能力差,应用转差频率矢量控制可增强电机对转矩的调节能力且无需电压补偿。

Abstract
This paper focuses on the matlab simulation of the asynchronous motor speed regulation system.
Firstly , this paper analyzes the main control method , position and working principle of the induction motor slip frequency control technology.
Secondly , this paper analysis the dynamic model of asynchronous motor and further introduces the coordinate transfer and the basic principle of motor slip frequency vector control system. At the same time , the simulation work to prove its feasibility.
Finally , according to analysis of the simulation results , the conclusions are as follows simply slip frequency control is always with poor load capacity , on the contrary the vector control applications can enhance the ability to regulate the motor of the torque and without pensation.
Key words : slip frequency , vector control , induction motor
