| 摘 要： | 电动汽车直接转矩模糊控制系统中 ,定子磁链观测器采用电压模型时 ,系统低速性能变差。针对这一问题 ,用基于定子电压、定子电流和转速的磁链观测器代替电压模型磁链观测器 ,使系统全速范围内性能良好。通过MAT LAB SIMULINK软件对采用不同磁链观测器的电动汽车直接转矩模糊控制系统进行建模与仿真并验证之。

| Abstract: | In a direct torque fuzzy control system of electric vehicle, when the voltage model is used as stator flux observer, the system's low speed performance becomes poor. So a new flux observer based on voltage, current and speed instead of voltage model observer improves the system performance in whole velocity range. The paper shows that it is possible to use MATLAB/SIMULINK software to model and simulate the fuzzy direct torque control system of electric vehicle using different kinds of flux observer. In this paper simulation results are given to verify it. |
