Abstract :
Active Disturbance Rejection Control (ADRC) and Sliding Mode Control (SMC) are two excellent kinds of control approaches in dealing with the uncertainties and outer disturbances of the system. In this paper, Attitude of an spacecraft is controlled by a second-order linear ADRC and a SMC with reaching law respectively. The difference of the track performance, disturbing resistance and the robustness between this two controllers are analyzed. Simulation results show that both the ADRC and the SMC can achieve very good track performance, disturbing resistance and robustness. Compared with the SMC, ADRC can achieve better control performance.
