“…Huang et al 19 studied the combination of tethered robots by the means of thruster control, which provided constant force to make the entire system stable. Some other classical control methods, such as LQG 20 and non-linear dynamic control 21 were adopted to implement the thruster-aid control for deployment of TSS. Besides these controllers, since thrusters make the system decoupled and actuated, distributed control 22 and sliding PID control 23 are also the potential methodologies theoretically.…”

This paper presents a sliding mode controller for the deployment of two-body tethered satellite system. A sliding surface design for underactuated system is employed to reconcile pure-tension control scheme with non-linear coupled deployment dynamics. The proposed sliding surface is strictly non-linear. Hence, the control scheme does not require linearization operation of tethered satellite system and can guarantee that all the system states converge to zero with arbitrary small errors. To deal with input constraint of pure-tension control, an adaption is introduced into the controller design to remove the negative effect caused by input constraint in stability analyses and ensures the feasibility of the proposed controller even though command input overtakes the tolerance of tension actuator. To avoid the chattering phenomena, the trivial sign function is removed from the switching input and replaced by the disturbance observer. Numerical results demonstrate the effectiveness of the proposed controller for the deployment of the tethered satellite system.
