“…In [8], an adaptive finite-time robust controller has been proposed to achieve the desirable configuration as well as the consensus of attitudes, but this controller did not deal with the unknown velocity states. Taking physical constraints into account, the finite-time synchronization distributed control for 6-DOF dynamics with external disturbances without velocity measurements was addressed in [9], and the relative position coordination tracking control for 6-DOF dynamics with communicate delays was investigated in [10], [11]. Nevertheless, the attitude synchronization distributed control without velocity measurements and the relative position coordination tracking control have not been considered simultaneously in the existing studies.…”

In this paper, the problem of distributed 6-DOF coordinated control for spacecraft formation is investigated. The dynamics of each spacecraft consisting of relative attitude and position motions are modeled into a unified Euler-Lagrange formulation. The formation consists one virtual leader and n spacecrafts, and the information switching among the formation members is described by a directed graph. A distributed coordination control protocol is proposed to guarantee the stability of the spacecraft formation in the presence of external disturbances, unmeasurable attitude angular and position velocities, and timevarying communication delays based on backstepping technique using time-delayed information. Further, to decrease the communication frequency of the spacecraft formation flying system, an event-triggered distributed coordination strategy is also developed to solve the 6-DOF coordinated control problem for spacecraft formation. The stability analyses of the obtained control algorithms are conducted through the Lyapunov method. Finally, the effectiveness and the ability of massive reducing the frequency of communication times of the proposed control scheme are illustrated through numerical simulations.

“…In Ref. [ 31 ], the problem of distributed finite time 6-DOF synchronization control for multiple spacecraft in the presence of external disturbances and parameter uncertainty was investigated, and 6-DOF coupled motion model was the Euler–Lagrange form. Nevertheless, to the best of our knowledge, there is little research on the dual quaternions-based adaptive coordinated controller design for multiple spacecraft.…”

A distributed six-degree-of-freedom (6-DOF) cooperative control for multiple spacecraft formation is investigated considering parametric uncertainties, external disturbances, and time-varying communication delays. Unit dual quaternions are used to describe the kinematics and dynamics models of the 6-DOF relative motion of the spacecraft. A distributed coordinated controller based on dual quaternions with time-varying communication delays is proposed. The unknown mass and inertia, as well as unknown disturbances, are then taken into account. An adaptive coordinated control law is developed by combining the coordinated control algorithm with an adaptive algorithm to compensate for parametric uncertainties and external disturbances. The Lyapunov method is used to prove that the tracking errors converge globally asymptotically. Numerical simulations show that the proposed method can realize cooperative control of attitude and orbit for the multi-spacecraft formation.

“…Attitude control is a significant research topic for mission accomplishment in advanced aerospace projects such as earth surveillance, space-based interferometry, and spacecraft formation flying etc., which has been therefore extensively studied. The theoretical and engineering investigations through the existing literature mainly focus on the robustness to disturbances and uncertainties [1][2][3], rigid-flexible nonlinear characteristics [4][5][6], fault-tolerant capacity [7,8], angular velocity free schemes [9,10] and convergent rate performance [11][12][13][14][15]. In this respect, it is desirable to develop reliable control strategy to endow the attitude control system high performance and fault-tolerant capacity.…”

This paper investigates the prescribed performance fault‐tolerant attitude tracking control for flexible spacecraft under limited communication network, where the controller and the actuator are connected via wireless network. The hysteresis quantizer is employed to quantize the control signal, which can reduce the communication burden of the network onboard. First, a novel iterative learning observer is developed by combining with neural‐network approximation method to reconstruct the actuator faults and estimate the unmeasurable nonlinear rigid‐flexible dynamics simultaneously. Then, the signal quantization technique is introduced for control command quantization, and the concerned parametric quantization error is given. Based on the learning observer output, prescribed performance design procedure, and a quantization error compensation method, an active fault‐tolerant control strategy is developed for flexible spacecraft attitude tracking to deal with actuator faults, unmeasurable system nonlinearity, quantization errors, and external disturbances. The stability analysis of the closed‐loop system proves that the quantization errors, modal vibrations, disturbances can be effectively rejected, moreover, the convergence of the transformed performance states and angular velocity states can be guaranteed, which achieves the tracking problem with predetermined transient‐state and steady‐state performance requirements. Finally, a numerical simulation is conducted to illustrate the validness of the proposed control strategy.
