摘要:

控制拉格朗日和匹配技术的稳定化的相对平衡和平衡的离散力学系统的对称性以及对称性破缺。有趣的新现象出现在控制拉格朗日方法在离散的情况下,不存在于连续的理论。特别是,为了使离散理论有效,可以适当地选择动量水平,或者,引入一个新的参数到受控拉格朗日来完成动力学匹配过程。具体而言,新的条款,在控制的形状方程是必要的潜在的匹配在离散设置。本文以倾斜小车-摆系统的稳定问题为例说明了这一理论。本文还讨论了数字和模型预测控制器。

英文摘要:

Controlled Lagrangian and matching techniques are developed for the stabilization of relative equilibria and equilibria of discrete mechanical systems with symmetry as well as broken symmetry. Interesting new phenomena arise in the controlled Lagrangian approach in the discrete context that are not present in the continuous theory. In particular, to make the discrete theory effective, one can make an appropriate selection of momentum levels or, alternatively, introduce a new parameter into the controlled Lagrangian to complete the kinetic matching procedure. Specifically, new terms in the controlled shape equation that are necessary for potential matching in the discrete setting are introduced. The theory is illustrated with the problem of stabilization of the cart-pendulum system on an incline. The paper also discusses digital and model predictive controllers.
