“…From [17], it can be known that this chattering is resulted from the external disturbance. The proposed rendezvous law (18), however, can resist this bad influence effectively. Control inputs are illustrated in Fig.3 (c) as well as adaptive elements of three control channels in the proposed rendezvous law are depicted in Fig.3 (d).…”

“…From the control algorithm (16) ~ (18) and the dual-layer structure (46) ~ (49), one can imply that the proposed rendezvous scheme requires no information about the upper bound of the lumped disturbance. Due to its inherent characteristic of strong robustness, the proposed STL algorithm can resist the external disturbance with highly efficiency, while the dual-layer structure can seek the upper bound of lumped disturbance autonomously.…”

“…Considering the case that the sensors cannot measure the relative velocity accurately, Wang and Ji [17] designed an integrated relative position and attitude control for spacecraft rendezvous with input-tostate (ISS) and finite-time convergence. Combining with robust control method and adaptation, Sun et al [18] proposed a novel relative position and attitude control method for spacecraft autonomous proximity. Moreover, other advanced rendezvous algorithms were designed and applied to overcome some problem in real engineering practice.…”

Considering the scenario that the obstinate and difficult-repaired sensor and actuator failure always occurs during the spacecraft rendezvous guidance phase and may cause terrible performance, this paper studies the fault-tolerant guidance method and proposes a velocity-free guidance algorithm. Above guidance law is based on a dual-layer adaptive multi-variable super-twisting-like algorithm, where two waving gains are introduced to autonomously adjust the system trajectory subject to the relative velocity. Hence, the complex parameter selection problem is overcome. Moreover, to overcome the sensor fault in relative-velocity channel, a robust observer which can drive the velocity error converge to zero in a small finite time is presented. To test the effectiveness and stability of the proposed guidance law, considering actuator faults, second-order dynamics and saturation, numerical simulations including comparisons and Monte-Carlo are carried out and the results demonstrate above properties.

Removing a limited number of large debris can significantly reduce space debris risks. These bodies are generally exposed to extreme environmental disturbance torques or consecutive accidents due to their large wet area, which causes them to experience accelerated high-rate tumbling motion. The existing literature has adequately explored the approximation operations with non-cooperative targets exhibiting 3-axis tumbling motion. However, the research gap lies in the lack of attention given to addressing this approximation for targets undergoing accelerated motion. Agile, accurate, and large-angle maneuvers are three common necessities for safely capturing such targets. Changes in the moment of inertia brought on by fuel slushing cannot be disregarded during such a maneuver. To deal with nonlinearities, adverse coupling effects, actuator saturation constraints, time-varying moment of inertia, and external disturbances that worsen during accelerated agile large-angle maneuvers, a novel adaptive control approach is developed in this paper. The controller's main advantage is its adjustable desired acceleration, which maintains its performance even when dealing with accelerated motion. The control law is directly synthesized from the nonlinear relative equations of motion, without any linearization or simplification of the system dynamics, making it robust to a variety of orbital elements and target behaviors. Adaptation laws are extracted from the Lyapunov stability theorem in a way that guarantees asymptotic stability. Moreover, control actuator roles (delay, saturation, and allocation) are accounted for in modeling and simulation. Finally, a comprehensive numerical simulation based on three different realistic and strict scenarios is carried out to demonstrate the effectiveness and performance of the proposed control approach. The controller's robustness against time-varying dynamic parameters (sharp and sudden change, smooth and slow change, and periodic change) is extensively demonstrated through simulation.
