Attitude Control of Spacecraft Using L1 Adaptive Control in the Presence of Actuator and Disturbances

Abstract

In this paper, attitude control of spacecraft in the presence of uncertainties and disturbances has been simulated. Access to rapid maneuver in spacecraft decreased accuracy. Therefore, to enhance the accuracy of spacecraft rapid maneuver and to resist uncertainties the adaptive control L1 is suggested. The controller is able to control the attitude of the spacecraft due to rapid adaptation and robustness against uncertainties simultaneously. In this paper, an adaptive control of L1 is compared with reference model. The dynamics of the multi-input-multi-output system. Simulation results show the desired performance of the L1 controller.
