非完整力学系统的约束控制

Constraint Control of Nonholonomic Mechanical Systems

Vakhtang Putkaradze, Stuart Rogers

摘要:

利用不完整约束本身作为控制,导出了非完整力学系统的最优控制公式。我们专注于Suslov的问题,它被定义为一个刚体的运动与消失的投影的身体框架角速度在一个给定的方向$\boldsymbolξ$。我们推导出最优控制配方,首先为任意组,然后在经典实现的旋转群$SO(3)$的Suslov的问题。我们表明,它是可能的控制系统使用的约束$\boldsymbolξ(t)$和演示的数值例子中,系统跟踪相当复杂的轨迹,如螺旋。

英文摘要:

We derive an optimal control formulation for a nonholonomic mechanical system using the nonholonomic constraint itself as the control. We focus on Suslov's problem, which is defined as the motion of a rigid body with a vanishing projection of the body frame angular velocity on a given direction $\boldsymbolξ$. We derive the optimal control formulation, first for an arbitrary group, and then in the classical realization of Suslov's problem for the rotation group $SO(3)$. We show that it is possible to control the system using the constraint $\boldsymbolξ(t)$ and demonstrate numerical examples in which the system tracks quite complex trajectories such as a spiral.
