摘要
噪音是开关磁阻电机应用中的一大难题。针对开关磁阻电机运行过程中转矩脉动较大的问题,采用有限元计算方法所得到的电机模型,在MATLAB中进行开关磁阻电机模糊PI直接瞬时转矩控制的仿真实验。采用Ansoft电磁场仿真软件,搭建了三相4/6开关磁阻电机,并将得到的磁链数据导入MATLAB电机模型中。随后,利用该模型搭建模糊PI直接瞬时转矩控制的Simulink仿真实验平台。实验结果发现,系统在0.01 s时开始响应,转矩浮动在0.05~0.1 Nom之间。该结果表明,将有限元得到的电机模型应用到模糊PI直接瞬时转矩控制的仿真实验中时,可以提高系统响应,并有效抑制转矩脉动。
Noise is a big problem for switched reluctance motor. Aiming at the problem of large torque ripple in the operation of switched reluctance motor, the motor model obtained by finite element calculation was used to conduct the fuzzy PI direct instantaneous torque control of switched reluctance motor in MATLAB simulation. The Ansoft electromagnetic field simulation software was adopted to establish a three-phase 4/6 switched reluctance motor, and the obtained flux linkage data was introduced into the MATLAB motor model. Subsequently, a Simulink simulation experimental platform with a fuzzy PI direct instantaneous torque control was set up by the obtained model. Simulation results showed the system started to respond at 0.01 s and the torque was floating between 0.05~0.1 Nom. Therefore, the application of the motor model obtained by finite element to the simulation experiment of fuzzy PI direct instantaneous torque control could improve the system response and effectively suppressed the torque ripple.
