We report theoretical and experimental results on the stabilization of unstable steady states in a CO2 laser with feedback. Periodic and chaotic oscillations have been suppressed by means of a control loop consisting of a high-pass filter, known as washout filter. Although the filter characteristics are determined on the basis of linear analysis, taking into account the problem of robustness with respect to parameter changes, the present control strategy provides a large attractive domain in the phase space.
我们报告了关于具有反馈的二氧化碳激光器中不稳定稳态稳定化的理论和实验结果。通过由高通滤波器（称为洗出滤波器）组成的控制回路抑制了周期性和混沌振荡。尽管滤波器特性是基于线性分析确定的，但考虑到参数变化的鲁棒性问题，当前的控制策略在相空间中提供了一个很大的吸引域。
