Control-Structure Integrated Design

This article presents an optimization- based approach to the integrated control and structural design of dynamical systems. The framework of a general formulation is developed, which lends itself directly to the design of structural plants requiring control. This method can employ classical and modern control techniques in the time or frequency domain. A performance norm that possesses full knowledge of the control and structural design characteristics is developed. This article explicitly addresses the disturbance-rejection and commandfollowing performance of the system, in addition to the vibration level and the control effort. The design methodology is demonstrated by simultaneously performing the structural and control designs of a truss-like spacecraft undergoing a rotational maneuver.
