开关磁阻电机自抗扰控制研究

Research on Active Disturbance Rejection Control of Switched Reluctance Motor

开关磁阻电机具有很多优良的特性,但存在较大的转矩脉动。以开关磁阻电机的数学模型和自抗扰控制理论为基础,设计了开关磁阻电机自抗扰控制系统,并采用Matlab对系统进行了仿真。仿真结果表明,该自抗扰控制方案对系统参数变化具有很强的鲁棒性,可以有效地抑制开关磁阻电机的转矩脉动。

The switched reluctance motor has many excellent characteristics, but large torque ripple exists. Based on the mathematical model of SRM and the theory of active disturbance rejection control, designs a ADRC system of SRM, and the simulation with Matlab indicates that the ADRC scheme has strong robustness to the changes of system parameter, and can effectively restrain the torque ripple of SRM.
