“…To guarantee the high control performance, reliability, and safety of spacecraft formation flying systems, fault diagnosis and fault-tolerant control (FTC) are challenging problems that need to be handled urgently for spacecraft formation flying systems in practice. In view of these, fault diagnosis and FTC for spacecraft formation control systems have attracted considerable 2 of 18 attention in both research and practical applications during the past decade, and great progress has been achieved in recently published work in the literature [8][9][10][11][12][13][14][15][16].…”

“…The reconfigurable FTC approach in different failure modes could effectively maintain the spacecraft formation configuration. In [15], a decentralized FTC algorithm was proposed for the three-inline array tethered spacecraft formation system. In [16], two new adaptive FTC algorithms were developed to estimate the effectiveness of the actuator, spacecraft masses, and the upper bound of external disturbances for spacecraft formation control systems that are subject to time-varying communication delays.…”

This paper investigates the issues of iterative learning algorithm-based robust thruster fault reconstruction and reconfigurable fault-tolerant control for spacecraft formation flying systems subject to space perturbations. Motivated by sliding mode methodology, a novel iterative learning observer (ILO) was developed to robustly reconstruct the thruster faults. Based on the fault signals obtained from the ILO, a learning output–feedback fault-tolerant control (LOF2TC) approach was explored such that the closed-loop spacecraft formation configuration was accurately maintained in the presence of space perturbations and thruster faults. Numerical simulations were employed to demonstrate the effectiveness and superiority of the proposed ILO-based fault-reconstructing approach and LOF2TC-based configuration maintenance approach for spacecraft formation flying systems.

“…Thorough studies on employing robust observers for online fault reconstruction purposes reveal a new observer‐based fault estimation method and its use in FTC applications [4, 5]. Tackling the robustness of the reconstructed faults against undesired measurement noise, uncertainties, and system non‐linearity is an essential task in fault estimator design [3, 6]. In this regard, the disturbance decoupling capability of the unknown input observer (UIO) makes it useful for robust FD/FTC application.…”

“…Kim and Hall studied triangle tethered formation based on input-state feedback linearization in [5], but have not considered the perturbation effects. Besides the centralized control scheme, decentralised fault-tolerant control is proposed by Zhang et al [16]. Based on the previous research, it is found that the connected tethers in triangle formation can be considered as a rigid elastic link during the entire deployment, because of the centripetal force caused by spinning.…”

The tethered formation system has been widely studied due to its extensive use in aerospace engineering, such as Earth observation, orbital location, and deep space exploration. The deployment of such a multitethered system is a problem because of the oscillations and complex formation maintenance caused by the space tether's elasticity and flexibility. In this article, a triangle tethered formation system is modeled, and an exact stable condition for the system's maintaining is carefully analyzed, which is given as the desired trajectories; then, a new control scheme is designed for its spinning deployment and stable maintenance. In the proposed scheme, a novel second-order sliding mode controller is given with a designed nonsingular sliding-variable. Based on the theoretical proof, the addressed sliding variable from the arbitrary initial condition can converge to the manifold in finite time, and then sliding to the equilibrium in finite time as well. The simulation results show that compared with classic second sliding-mode control, the proposed scheme can speed up the convergence of the states and sliding variables.
