ABSTRACT. THE OBJECTIVE OF THIS WORK IS TO DESCRIBE THE DESIGN AND THE IMPLEMENTATION OF AN EXPERIMENT TO STUDY THE DYNAMICS AND THE POSITION CONTROL OF AN UNCONSTRAINED MULTI-LINK FLEXIBLE STRUCTURE. THE EXPERIMENTAL APPARATUS WAS DESIGNED TO BE REPRESENTATIVE OF A FLEXIBLE SPACE STRUCTURE SUCH AS A SATELLITE WITH MULTIPLE FLEXIBLE APPENDAGES. WE DESCRIBE THE ANALYTICAL MODELING AND THE MODEL VALIDATION STUDIES CARRIED OUT THROUGH EXPERIMENTAL MODAL TESTING AND PARAMETRIC SYSTEM IDENTIFICATION STUDIES IN THE FREQUENCY DOMAIN. AN EXPERIMENTAL POSITION CONTROL WITH COLLOCATED SENSOR AND ACTUATOR IS ALSO DESCRIBED. THE CONTROL WAS IMPLEMENTED IN REAL TIME IN THE MATLAB.
KEYWORDS : FLEXIBLE STRUCTURES, MODAL ANALYSIS, IDENTIFICATION, CONTROL OF STRUCTURES.
