Abstract

As a simultaneous optimization problem of structure and control, cross sectional areas of a 3-D truss structure are optimized considering the minimization of the structural weight and its control cost under the stress constraint at the initial deformed state. A quadratic performance index as in the optimal regulator theory is adopted as a control cost, and it is minimized with structural weight fixed at a constant value in order to obtain a Pareto optimum solution of the two-objective problem. The optimization is carried out by the energy-ratio method and the stress constraint is treated by the stress-ratio method.
