研究了单自由度磁悬浮轴承的干扰抑制问题。为了不失一般性，用高斯白噪声信号来模拟干扰信号。以Matlab为设计平台，用遗传算法设计了PID控制器，给出了干扰抑制的仿真结果。结果表明，遗传算法整定参数的PID控制器具有响应快速、超调量小，对大扰动的抑制较好的特点。
研究瞭單自由度磁懸浮軸承的榦擾抑製問題。為瞭不失一般性，用高斯白譟聲信號來模擬榦擾信號。以Matlab為設計平檯，用遺傳算法設計瞭PID控製器，給齣瞭榦擾抑製的倣真結果。結果錶明，遺傳算法整定參數的PID控製器具有響應快速、超調量小，對大擾動的抑製較好的特點。

The interference suppression of the active magnetic bearing ( AMB) with single degree of freedom is studied in this paper.Gaussian white noise signal is employed to simulate the interfering signals in order to guarantee the interfering signals′generalization.A PID controller is designed by using the genetic algorithm ( GA) with MATLAB platform.The simulation re-sults show that the system with the PID controller whose parameters are set by GA has characteristics of quick response, small overshoot and good suppression of big interference.
