摘要
提出了以傅立叶级数为基础的开关磁阻电动机(SRM)的电感模型。计算结果与实际测量结果吻合,验证了该模型的准确性和适用性;同时运用该电感模型建立了开关磁阻电动机的非线性模型,并用于电机控制方式的研究,进一步验证了非线性模型的正确性。在建立非线性模型的基础上,对SRM的关断角进行优化,仿真结果符合优化的结论。
This paper proposes an inductance model to Switched Reluctance Motor（SRM）in terms of Fourier Series expression of phase self-inductance under the assumption of negligible mutual effect and various losses, and the result from the compare between computing data and experimental data demonstrates the accuracy and practicality of this model. Further, a SRM nonlinear mathematical model, based on the inductance model, is set up under Matlab/Simulink environment, and various control strategies are researched, which also verifies the SRM model＇s efficiency. The turn-off angle is optimized by using the SRM model, and the simulation result accords with the conclusion.
