Modeling and Simulation of Active Attitude Control for Satellites

One of the most important problem in satellite design is that of attitude stabilization and control, which is the combination of mathematics, dynamics, and control theory. Basic types of control systems are spin control, where the entire satellite is spun, dual-spin control, where the major porti...
