μ Synthesis for analog rig control system of tilting train

针对摆式列车数学模型的不确定性及倾摆控制系统设计的多目标要求 ,对摆式列车模拟试验装置的辨识数学模型分别用H∞ 方法和 μ方法设计三个鲁棒控制器 .同时探讨了在跟踪问题的鲁棒控制设计中加权函数选择的一般性原则 .仿真结果表明 ,鲁棒控制的H∞ 方法和 μ方法在处理具有各种不确定性的系统设计中均有良好的效果 ,但 μ方法在摄动下的干扰抑制性能比H∞

Considering the uncertainty of the identified mathematics model of the tilting train and the multiple design targets of declining control system, three robust controllers were synthesized for analog test rig of tilting train with H ∞ approach and μ approach. The general principle to find appropriate weight functions on robust controller design for tracking was discussed. The simulation results indicated that μ approach was more effective on disturbance attenuation than H ∞ approach under the condition of perturbations.
