Anosov parameter values for the triple linkage and a physical system with a uniformly chaotic attractor

First, the free frictionless dynamics of the triple linkage of Thurston and Weeks is proved to be Anosov on each positive energy level for a non-empty open set of parameter values. Second, in the presence of weak friction and any smooth potential, an open set of physically implementable feedback control laws are found for which the system possesses a uniformly hyperbolic attracting submanifold.
