摘要
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。
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.
