In this paper a simple four-bar mechanism model is developed to reconfigure through phase space connections.

Transitions between equal-energy unstable (but actively controlled) equilibria in principle require zero net energy input.

An objective function is used to seek transitions between unstable equilibria which approximate heteroclinic connections.

The four-bar mechanism then forms the basis for an elastic model of a smart buckling beam.
