Research on Nonlinear Model Identification of the Hydragas Suspension Based on Structure-selection Techniques

  • 摘要: 建立利用位移和速度的多项式来表示输出力的油气悬架模型。针对传统的最小二乘法在多项式形式的模型辨识中无法确定模型中的有效项的问题,提出了用误差减小比率的结构选择技术,来选择油气悬架模型多项式结构中的有效项并确定这些有效项的系数。以某型车辆的油气悬架为应用对象,结果表明利用这种基于误差减少比例的结构选择技术的模型辨识方法,能够用简洁的多项式结构和准确的系数表示油气悬架模型。
