| contents | Three-axis air-bearing based platform for small satellite attitude determination and control simulation J. Prado G. Bisiacchi E. Vicente M. Mesinas F. Contreras A. Juárez L. Reyes Ingeniería Bearing Sliding Masses Spherical Air Spacecraft Simulator Automatic Static Balancing A frictionless environment simulation platform, utilized for accomplishing three-axis attitude control tests in small satellites,is introduced. It is employed to develop, improve, and carry out objective tests of sensors, actuators, and algorithms in theexperimental framework. Different sensors (i.e. sun, earth, magnetometer, and an inertial measurement unit) are utilizedto assess three-axis deviations. A set of three inertial wheels is used as primary actuators for attitude control, together withthree mutually perpendicular magnetic coils intended for desaturation purposes, and as a backup control system. Accuratebalancing, through the platforms center of mass relocation into the geometrical center of the spherical air-bearing,significatively reduces gravitational torques, generating a virtually torque-free environment. A very practical balancingprocedure was developed for equilibrating the table in the local horizontal plane, with a reduced final residual torque. Awireless monitoring system was developed for on-line and post-processing analysis; attitude data are displayed and stored,allowing properly evaluate the sensors, actuators, and algorithms. A specifically designed onboard computer and a set ofmicrocontrollers are used to carry out attitude determination and control tasks in a distributed control scheme.The main components and subsystems of the simulation platform are described in detail. 2005 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47430306 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.3 Vol.3 |
