Adaptive Attitude Control of a Satellite with Bilateral Rotating Solar Arrays

As appendages continue to grow larger, the parameters of the coupling coefficient matric information plays an important role to ensure the success of the attitude control during satellite mission. Considering changes in the structural configuration caused by the rotation of bilateral solar arrays in remote satellites, this study proposes a controller design in the presence of coupling coefficient matric uncertainties based on adaptive feedback technique. Firstly, the dynamic equations of time-varying system are derived using Lagrange approach. After that, a controller is designed using adaptive feedback law with coupling coefficient matric estimation. The simulation results reveal that the attitude stabilization and tracking performance of the proposed algorithm is better than proportional derivative (PD) approach without identification.
