Evolutionary Design of Controlled Structures Systems

An evolutionary controls/structures design method is developed. The basis of the method is an accurate model formulation for dynamic compensator optimization and Genetic Algorithm based updating of sensor/actuat or placement and structural properties. One and three dimensional examples from the literature are used to validate the method. Frequency domain interpretation of the controlled structure systems provide physical insight as to how the objective is optimized. Several designs for a stellar interferometer precision structure are found for two different spectra of disturbance under assumed closed loop optical conditions. Physical limitations in achieving performance are given in terms of average system transfer function gain and system phase loss.
