A New Approach to the Analysis and Control of Large Space Structures. Phase 1.

Abstract

The large structures contemplated would be constructed in space. Because of the limitations on launching massive payloads, it is clear that these structures will be made of lightweight material and will necessarily be flexible and easily excited into vibrations. Analytical problems will arise in designing large space structures in which physically realistic and accurate solutions will be critical. Such designs must consider weight, sizes, stiffness, thermal and mechanical distortions, stresses due to gravity and positioning thrusts. Some specific analytical problems will involve vibration, heating and cooling, multidimensional control, and structural problems arising from random support motion and random fluctuations of the system dynamic properties. Keywords: Decomposition method, Distributed control, Heating, Space stations, Matrix Riccati equation, Nonlinear stochastic control, Partial differential equations, Vibration, Spacecraft. (jes)
