Adaptive Control of Truss Structures for Gossamer Spacecraft

Neural network-based adaptive control is considered for active control of a highly flexible truss structure which may be used to support solar sail membranes. The objective is to suppress unwanted vibrations in SAFE (Solar Array Flight Experiment) boom_ a test-bed located at NASA. Compared to previous tests that restrained truss structures in planar motion, full three dimensional motions are te...
