Satellite Attitude Control by Predictive Filtered Error in the Presence of Uncertainty and Modeled Disturbance

The aim of this study is investigating the satellite attitude control in the presence of uncertainty and disturbance causing a decrease in precision and maneuverability. L1 adaptive control is recommended for solving this problem. L1 is significantly effective and accurate because of bounding high-frequency signal affected by uncertainty or high adaptive gain. For illustrating L1 performance, this controller is compared to Model Reference Adaptive Control (MRAC). The dynamic system is linear and Single-Input-Single-Output (SISO). The results show the good performance of the suggested controller.
