采用加速度反馈的方法,可以在主动式悬挂设计中将一个任意刚度的车身弹簧考虑进去而不天其最优性。此外,在一个切实可行的简化方案中,其所需的车身位置的反馈可以通过车身相对于轮轴而不是相对于路面的测量而得到。这样做的同时,必然会引起性能稍许下降,从而形成一个具有简化反馈结构的次优系统。文中还讨论了性能指标中加权系数对最佳系统特征值的影响。
The acceleration feedback method can be used in the active suspension design will take into account the body stiffness of an arbitrary stiffness without optimal. In addition, in a practical and simplified solution, the required feedback of the body position can be obtained by measuring the body relative to the axle rather than the road surface. While doing so, it will inevitably cause a slight decrease in performance, resulting in a sub-optimal system with a simplified feedback structure. The article also discusses the influence of the weighted coefficients in the performance index on the optimal system eigenvalue.
