Abstract : "This paper studies the coordinated attitude control problem of synthetic aperture radar satellites and
proposes two types of terminal sliding mode control schemes. The first control law is investigated based on the
conventional non-singular terminal sliding mode approach and modified Rodrigues parameters with the consideration of signal quantization and communication delay. Based on the first control scheme, we develop the second
control method with an integral-based event triggering condition to reduce the updating frequency of the control
command from controllers to actuators. Finally, numerical simulation examples based on a cluster of three satellites
are presented to show the effectiveness of the proposed two designed control methods."
