摘要
为实现开关磁阻电机(SRM)低速与高速下不同控制方式的平滑切换,提出一种采用函数拟合法的相电流开通角、关断角以及电流斩波给定值协调控制的全转速范围控制方法。为抑制开关磁阻电机运行中的各种扰动,提高动态运行性能,将自抗扰控制应用于转速调节,构建了基于自抗扰控制的开关磁阻电机全转速段控制方式平滑切换调速系统。仿真结果表明所提方法能够协调控制开通角、关断角和电流斩波给定值,实现高、低速下控制方式的平滑切换,系统动态性能良好,达到了良好的控制效果。
In order to smoothly switch different control modes of switched reluctance motor under the condition of low speed and high speed, a novel scheme using function fitting method to control turn-on angle, turn-off angle and phase current chopping is proposed. The active disturbance rejection speed control system is structured for switched reluctance motor in order to restrain all kinds of disturbance and improve the dynamic performance. Simulation results indicate that the principle of the method is correct and the turn-on angle, turn-off angle and phase current chopping is coordinated to realize the smooth switching of different control modes with low speed and high speed. The dynamic performance of the system operates well.
