“This work studies the average control approach for the active attitude control of nanosatellites through the use of magnetorquers. Key concepts, constraints, and limitations due to the use of these actuators are presented. Then, based on a previous work employing an adaptive gain, a novel non-adaptive control law is proposed in order to decrease the energy consumption of the overall system without loss of stability. Theoretical guarantees regarding the ultimate bound of closed loop system trajectories are presented. Different simulation results illustrate the effectiveness of the proposed approach to achieve the desired attitude for different satellite configurations. A comparison between the new approach to the previous adaptive strategy available in the literature indicates that a con-
siderable energy economy could be reached, with values reaching 70% for some cases. Control signal saturation is considered in some of the simulated scenarios but not mitigated.
Keywords: Attitude Control, Quaternion representation, Average Theory, Non-linear.”<\/p>\n","protected":false},"excerpt":{"rendered":"
