| 摘 要： | 开关磁阻电动机由于其转矩是各相电流与转子位置角的高度非线性函数, 传统控制方法难以对其达到有效的控制. 应用模糊神经网络对开关磁阻电动机静态转矩特性逆模型进行离线学习, 学习完成之后, 在转矩分配函数的基础上, 实时在线优化出期望转矩所需要的相电流波形, 从而实现开关磁阻电动机的转矩线性、解耦、无脉动控制. 计算机仿真结果证明了这种方法的有效性.

| Abstract: | The primary disadvantage of an SRM was the higher torque ripple which was due to the highly nonlinear and discrete nature of torque production mechanism. Based on the experimental data of static torque characteristic, a fuzzy-neural network(FNN) was applied to the learning of its inverse model off line. Then according to the predefined torque distribution function (TDF), optimal current profile was real-time gained by the FNN on line, which resulted in a linear, decoupled, low ripple control of torque. The effectiveness of the proposed method was demonstrated by computer simulation results. |
