Controller Design for Flexible Spacecraft Attitude Tracking with Actuator Saturation

摘要

This paper considers the attitude tracking control problem of a class of flexible spacecraft with actuator saturations, and external disturbances. First, a sliding mode control (SMC) law is designed to achieve accurate attitude tracking with an adaptive algorithm. By means of the Barbalat lemma which is further used in this paper, the system stability and asymptotic attitude converging properties are guaranteed. The simulation results illustrate the efficiency of the theoretical results.
