在研究开关磁阻电机直接转矩控制系统的基础上,以MATLAB软件作为仿真平台,应用其自身的SIMULINK/S_Function工具来实现该系统中的扇区判断、开关矢量选择等模块的功能,并分别给出其具体实现算法,加快了系统的仿真速度,同时配合封装技术,简化系统结构,增强其直观性。仿真结果显示,磁链运行轨迹呈圆形,转矩、转速控制效果达到预期,验证了该建模方式的合理性和有效性。

Based on the study on Direct Torque Control system of Switched Reluctance Motor, taking MATLAB software as the simulation platform, using SIMULINK/S Function to achieve the function, such as sectors judgment, selection of switching vector, etc, and respectively giving their algorithm in detail, speeding up simulation speed of the system, in conjunction with the packaging technology, simplifying structure the structure the system, and enhancing their intuitive. The simulation results show that the flux trajectory is a circular, and the torque and speed control results live up to expectations, which verify the rationality and effectiveness of the modeling method.
