| 摘 要： | 针对传统的直接转矩控制中存在转矩、定子磁链波动大的问题,提出了一种结合空间矢量调制的模糊神经网络直接转矩控制方法。该方法运用模糊神经网络得到期望的任意相位空间电压矢量,再结合空间矢量调制直接对逆变器的开关状态进行控制,以达到减小转矩、定子磁链波动的目的。最后以TMS320F240为核心搭建了直接转矩控制系统,通过采集实验数据分析结果表明,直接转矩控制系统与传统的直接转矩控制系统相比,磁链和转矩波动明显减少,并且保持了转矩和速度的响应速度。

| Abstract: | This paper is concentrated on the problem of torque and stator flux linkage wide fluctuation.in traditional DTC and submits a new control method,which combine space vector modulation,fuzzy-neural network and DTC.It is based on the variation of flux linkage of motor's stator,the variation of torque and the position of motor's stator,gets a anticipant space vector of arbitrary phase by using the fuzzy-neural network,and then finds the optimal method to control the state of inverter switch by combined with spa... |
