Minimal Mass Structures for Control

Minimal Mass Structures for ControlRobert SkeltonProfessor

San Diego, CA 92093An optimization of a structure before, and independent of, control design leads to high energy controllers with little cooperation between the dynamics of the controller and the dynamics of the structure. Some optimization problems have been solved to minimize mass while maintaining a high degree of controllability. Two examples are given: Optimal structures under compressive loads and optimal structures under bending loads. The bending case solves a problem that has been open since the work of Michell in 1904, when he solved the infinitely complex case (a continuum of material), leaving the optimal discrete case open.
