Sensitivity analysis is an extremely powerful tool in many applications such as in the optimization of the dynamics of multibody systems with gradient-based methods. Sensitivity calculations are computationally burdensome and, depending on the method chosen for differentiation and the set of dynamic equations, they could result highly inefficient. Semi-recursive dynamic methods are seldom studied analytically in terms of sensitivity analysis due to their complexity, even though their dynamic performance is usually among the most efficient.

一种用于多体动力学的半递归 ODE 公式敏感性分析的分析方法



灵敏度分析在许多应用中都是一个非常强大的工具,例如使用基于梯度的方法优化多体系统的动力学。灵敏度计算在计算上很繁琐,并且根据选择的微分方法和动态方程组,它们可能会导致效率非常低。由于半递归动态方法的复杂性,很少在敏感性分析方面进行分析研究,尽管它们的动态性能通常是最有效的。
