Stochastic Control in Structural Design,
Abstract
Deterministic optimal control has contributed to the field of structural optimization through the introduction of new concepts, alternative ways of viewing design problems and a systematic methodology for solving design problems. It remains to show the applicability of stochastic control to the probabilistic structural optimization problem. Here the applicability is not so self evident but its usefulness can be demonstrated. The paper examines open-loop, closed-loop, open-loop feedback and m-measurement feedback control policies and gives the optimal result for the general nonlinear structural optimization problem. The special linear-quadratic problem is examined along with numerical approaches to solving the general nonlinear problem, including the method of stochastic approximation. The design of members in flexure and compression is used to illustrate the methodology. (Author)
