摘要
介绍了永磁同步电机的数学模型和直接转矩控制(DTC)的基本原理,并在MATLAB/SIMULINK环境下,搭建了基于s-fuction的永磁同步电机直接转矩控制系统的仿真模型,其中的电机模型、反馈控制和驱动电路都是由s-fuction编程实现的。最后,整个系统进行了仿真研究,结果表明该系统定子磁链接近圆形,具有良好的动静态性能。
This thesis stated the mathematical model and the basic principle of direct torque control of Permanent Magnet Synchronous Motor（PMSM） and established the simulated DTC model of PMSM based on s-fuction with MATLAB/SIMULINK, The model of motor and feedback control and driving circuit were programabled by s-fuction. Finally, some simulations were carried out to the whole control system, and the result proved that the stator flux was close to roundness and the system had good performance both in steady and dynamic state.
