Abstract
Distributed parameter methods can offer unique advantages in combined structures-control optimization, particularly in the preliminary design phase where at present complex computer programs based on large-dimension Finite Element Models are currently in vogue, replacing them by closed-form analytic expressions for performance criteria in terms of the structure/controls parameters. In this paper we present an explicit closed-form expression for a lattice-truss clamped at one end with co-located sensors and actuators at the other end, using an equivalent anisotropic Timoshenko beam model. Some generic controls/structures optimization problems are shown to be tractable analytically, exploiting this expression.
