开关磁阻电机运行噪声的研究

Research on the operating noises of DTC

针对开关磁阻电动机运行的振动和噪声问题,在对开关磁阻电机非线性模型进行分析的基础上,将直接转矩控制方法应用到SRM的控制当中。仿真结果表明,该方法有效地抑制了SRM的转矩脉动,明显地降低了SRM的运行噪声。

As to the problems of operating noises and vibrations,this paper applied the Direct Torque Control（DTC） technique to SRM＇s controlling,based on the analysis of the nonlinear model of SRM.The simulation results showed that this method restrained its torque fluctuate effectively,and reduced its operating noises obviously.
