论文摘要
强制变分集成剂是通过对受外部力的系统的Lagrange-d'Alembt原理的离散化来给出的,并证明对复杂动力学系统的数值模拟研究有用。在本文中,我们使用几何力学技术对一个被动步行者进行了脚踏板的模型,并为系统构建了强制变异积分器。此外,我们提出了一种基于离散力学的简单混合构成强制性的Lagrangian系统,用于生成(本地)最佳控制策略的方法,该方法应用于轨迹跟踪问题中的脚部滑移的受控步行者。
Forced variational integrators are given by the discretization of the Lagrange-d'Alembert principle for systems subject to external forces, and have proved useful for numerical simulation studies of complex dynamical systems. In this paper we model a passive walker with foot slip by using techniques of geometric mechanics, and we construct forced variational integrators for the system. Moreover, we present a methodology for generating (locally) optimal control policies for simple hybrid holonomically constrained forced Lagrangian systems, based on discrete mechanics, applied to a controlled walker with foot slip in a trajectory tracking problem.
