|Speaker:||Controlling a mechanical system by active constraints, Penn State|
|A mechanical system can controlled by applying external forces, or by directly assigning the values of some of the components as functions of time.
This second approach is more natural in various cases, such as the control of a swing, a ski on a narrow trail, or the locomotion of a deformable body in a perfect fluid.
All these examples can be described by the same mathematical framework, involving a foliation on a Riemann manifold. The geometric properties of the foliation determine the algebraic form of of the dynamical equations, and the maneuvers which one needs to perform in order to control or stabilize the system.|
