Abstract: This paper introduces and comments current methodology applied to the field of Inte-grated Structure / Control Design from both a practical viewpoint and a mathematical viewpoint by a review of the published literature. In the literature, the variety of proposed interdisciplinary objective functions and synthesis methods reflects the multi-disciplinary nature of the problem. Approaches to the problem can generally be grouped into three categories: the sequential methods, the simultaneous methods, and multilevel optimization methods. A discussion of the formulation of performance indices or cost function from these methods is presented in this paper, together with typical results. The multilevel optimizaiton techniques have been found to offer a promising technique as opposed to other integrated design methods. Analytical expressions for optimal sensitivity derivatives related to multilevle optimization are outlined and discussed. The strong tendency is for the beneficial integrated design technology to be used in large orbiting space structure and active controlled, high performance aircraft design.

Key words: integrated design, aeroservoelasticity, multilevel linear decomposition
