Abstract
THIS RESEARCH SHALL FOCUS ON TWO IMPROVEMENTS TO THE CURRENTSTATE OF MODELING AND SHAPE CONTROL OF LARGE SPACE STRUCTURES: (1) THE USE OF FREQUENCY DOMAIN/SPECTRAL FACTORIZATION METHODS FOR THE DEVELOPMENT OF SHAPE CONTROL LAWS: AND (2) THE USE OF ADVANCED METHODS, INCLUDING HOMOGENIZATION, OR THE REDUCTION OF COMPLEXITY OF THE MODELSOF LARGE SPACE STRUCTURES WITH REGULAR LATTICE STRUCTURE. THE APPROACH WILL BE TO ADAPT SOME PROVEN ALGORITHMS OF DAVIS AND STINGER FOR OPTIMAL GAIN COMPUTATION BY SPECTRAL FACTORIZATION TO A GENERIC MODEL OF A LARGE, FLEXIBLE STRUCTURE. IN THE SECOND PART OF THE WORK WE SHALL ASSESS RELEVANCE OF HOMOGENIZATION ASYMPTOTIC ANALYSIS TO THE SIMPLIFICATION OF MODELS OF SOME TYPICAL LARGE, LATTICE STRUCTURES PLANNED FOR SPACE APPLICATIONS.
