Abstract:

This report summarizes new results on spacecraft dynamics and control. Perturbation methods are presented for computing nonlinear open and closed loop optimal maneuver control. Homotopy optimization algorithms are presented for tuning linear regulators vis-a-vis eigenvalue placement and robustness. A simultaneous structurecontroller design optimization algorithm is developed. Keywords active control structural analysis optimization integrated design spacecraft dynamics.
