Modeling Simulation and Test Beds
摘要
Ground-based validation of spaceborne momentum control systems and the attitude control systems that depend upon them offers a unique set of challenges. Computer simulations must include a variety of nonlinear phenomena found in momentum devices, which fundamentally limits the way these simulations can be architected. And because momentum systems rely on the conservation of angular momentum for proper operation, hardware-in-the-loop test facilities must reproduce the dynamics of a free body with great precision.
