Abstract
The satellite attitude control system is considered one of the most critical to guarantee the fulfillment of the functionalities expected in the use of these artifacts. Furthermore, the use of enlarged solar panels in order to support the increasing consumption of energy, and the fact that the restriction imposed on the weight of these items, due to the cost associated with launching them into orbit, results on thinner and more flexible structures. These items are subjected to undesirable vibrations that, if not controlled and maintained within acceptable minimum levels, can impact the accomplishment of the mission. Thus, the objective of this paper is to present the development of a Proportional-Integral-Derivative (PID) controller, using different optimization algorithms to find optimal values of its parameters. Two optimization techniques were tested: bioinspired algorithm and fmincon of MATLAB software. The mathematical modeling used for the rigid-flexible satellite was based on the mass-spring method. The results were compared with the ones obtained with the use of a Linear-Quadratic Regulator (LQR) to show the efficiency of the proposed tuning procedure.
