“…Numerical simulations based on a real case study were reported to validate the results presented, in scenarios spacing from ideal to adverse situations. Future work is aimed at explicitly providing robustness to the overall scheme, to tackle model inaccuracies, model parameter variations (e.g., due to fuel consumption) and unknown or unmodeled disturbances (e.g., solar and magnetic torque effects), as well as considering flexible spacecrafts (Zhu, Guo, Qiao, & Li, 2019).…”

“…In practical engineering, multiple disturbances with different characteristics are present, which motivates the studies of CHADC methods [14], [15]. In the framework of CHADC, an enhanced anti-disturbance control law is proposed for the attitude control system of flexible spacecrafts [16]. Recently, a composite anti-disturbance position and attitude control method is proposed for spacecrafts in the presence of parametric uncertainty and rigid-flexible coupling [17].…”

When tracking a tumbling non-cooperative target, the position and attitude maneuver control with high-precision as well as fast-response performances is required for flexible spacecrafts. However, the unknown rigid-flexible coupling and model uncertainties will degrade the control performances significantly. Therefore, this paper proposes a refined disturbance rejection-based composite control method for spacecraft position and attitude tracking. First of all, the disturbances including the rigid-flexible coupling and model uncertainties are described by an exogenous model by fully using the partially known disturbance information (e.g., modal frequency and damping). Then, a novel exogenous model-based sliding mode disturbance observer (SMDO) is proposed to achieve the refined disturbance estimation. Next, by combining the SMDO in the feedforward loop and an adaptive terminal sliding mode control (ATSMC) in the feedback loop, a finite-time composite control law is proposed to ensure the fast disturbance rejection and position/attitude tracking simultaneously. In the composite controller, a novel nonsingular terminal sliding mode surface with arctangent function is proposed. Moreover, a time-varying boundary Lyapunov function (BLF) is designed to preassign the transient and steady-state performances of sliding mode surface. Finally, the effectiveness of proposed method is verified via numerical simulation.INDEX TERMS Spacecraft position and attitude tracking, tumbling non-cooperative target, rigid-flexible coupling, sliding mode disturbance observer (SMDO), composite control.

“…For systems subject to multiple disturbances and fault/disturbance hybrids, the composite hierarchical anti‐disturbance control (CHADC) approach has been proposed. This approach has been shown to be effective for simultaneous attenuation and compensation of multiple sources of heterogeneous disturbances in a variety of engineering problems 23‐26 . However, this approach is yet to be applied in distributed estimation problems for networked systems.…”

Disturbances and attacks co‐exist widely in networked systems. Distributed state estimation of networked systems in the simultaneous presence of disturbances and attacks has been widely recognized as a challenging issue. In this article, an enhanced three‐stage approach for the detection and rejection of attacks is established for networked systems subject to multiple disturbances and false data injection (FDI) attacks. First, a multi‐layer distributed estimator with a disturbance observer layer is proposed. Then, an optimal observer‐based attack detection scheme is designed to specify an attack detection logic. After disturbance rejection and attack detection, an attack‐resilient estimator with a dynamic detection‐triggered structure is proposed to actively reject FDI attacks online. This three‐stage approach effectively separates the influence of disturbances and attacks in the distributed estimation process, enabling multiple heterogeneous disturbances and attacks across the sensor network to be rejected. A numeric example and comparisons are provided to illustrate the effectiveness of the proposed approach.
