| Abstract | The ever-increasing use of artificial satellites in both the study of terrestrial and space phenomena is demanding a search for increasingly accurate and reliable pointing systems. Attitude control systems rely on sensors and actuators that follow these requirements, but its cost is still high, with little tendency to fall. It is common nowadays to employ reaction wheels for attitude control that provide wide range of torque magnitude, high reliability and little power consumption. The wheels are composed by a Brushless DC motor (BLDC) whose rotor is attached to a flywheel. The low torque generated by the motor and the high inertia causes the wheel to accelerate or decelerate at very low rates. However, the bearing friction causes the response of wheel to be non-linear, which may compromise the stability and precision of the control system as a whole. This work presents a characterization of a reaction wheel of SunSpace Co., maximum capacity of 0.65 Nms, in order to estimate their friction parameters. It used a friction model that takes into account the Coulomb friction, viscous friction and static friction, according to Stribeck formulation. The parameters were estimated by means of a nonlinear batch least squares procedure, from data raised experimentally. The results have shown wide agreement with the experimental data, and were also close to a deterministic model, previously obtained for this wheel. This model was then employed in a Dynamic Model Compensator (DMC) control, which successfully reduced the attitude steady state error of an instrumented one-axis air-bearing table. |
