Control-structure integrated design with closed-form design metrics using physical programming

摘要

The technological area of control-structure integrated design (CSID) has witnessed significant evolution over the part decade and a half. ^This paper builds on recent developments in the area of computational optimization, and on new analytical methods developed herein, to make three distinct but synergistic contributions. ^First, this paper explores the application of the physical programming optimization method to the CSID problem. ^Second, a new approach is developed for the closed-form evaluation of time-domain performance metrics for high-order systems (e.g., settling-time). ^Third, a method for design-variabie-linking that uses splines is proposed and is shown to be computationally beneficial while also leading to more physically meaningful structural designs. ^The numerical results obtained for a controlled idealized rotating structure suggest that the analytical developments of this paper might have practical applicability. ^(Author)
