Summary: This paper investigates the simplified electromagnetic force/torque model and coupled orbit-attitude dynamics modeling in spacecraft electromagnetic docking, and proposes an improved sliding mode control scheme based on planned trajectory. The research shows that dividing the tracking process of relative orbit and attitude into three parts and using a sliding mode control strategy can solve the tracking problem effectively.

Summary: This article studies the appointed-time attitude tracking control of the spacecraft on the special orthogonal group, considering the attitude forbidden zone, parameter uncertainties, and external disturbances. A novel projection function and reduced dimensional vector are proposed, and a set of control schemes is constructed to ensure both attitude constraint and appointed-time control performance.

Summary: Fractionated satellite architectures go beyond the current trend of cooperating multiple small satellites, requiring the subsystems of all satellites to self-organize and cooperate among themselves. However, this introduces new challenges, such as how to perform closed-loop control of a satellite over a network of subsystems in a networked predictive formation control scenario.

Summary: This paper studies the fault monitoring problem of a spacecraft control moment gyro (CMG) in complex environments based on the data-driven method. A slice residual attention network (SRAN) is proposed to fully capture the edge features of images while satisfying the learning efficiency. Experimental results show that SRAN has good fault monitoring capability and ideal robustness.

Summary: This work presents a strategy for enhancing the performance and robustness of autonomous spacecraft by combining tube-based model predictive control (MPC) with uncertainty identification. The proposed algorithm measures and predicts the uncertainty of the system's exogenous input online, allowing the robust tube to be adjusted accordingly. Results show improved performance and flexibility compared to the standard algorithm.

Summary: This paper focuses on magnetic attitude control of spacecraft and proposes an approach to increase the duty cycle of magnetic rods while reducing the rate of collecting magnetometer data, leading to reduced maneuver time and power consumption. The effectiveness of the method is verified through Monte Carlo simulations and data collected from the CASSIOPE spacecraft.

Summary: This study aimed to design a LMI-based robust control system and a failure identification method for small spacecraft. The proposed method is capable of withstanding failure in the actuation system. The main objective was to design an H infinity controller that considered parametric uncertainties and matched failure of the actuation system, and to propose a fault detection method based on sliding mode observers for spacecraft stabilization.

Summary: This study investigates the problem of attitude takeover control of spacecraft using cellular satellites with limited communication, actuator faults, and input saturation. A control strategy combining event-triggered control and fuzzy logic systems is developed to address uncertainties and disturbances in the system, showing guaranteed boundedness in closed-loop systems.

Summary: The new GCMG design offers a more efficient way to avoid singularities while maintaining the advantages of SGCMGs, using only five DoFs compared to the eight DoFs in a VSCMG cluster. Numerical simulations showed that the GCMG design is considerably more power-efficient and achieves a better gimbal configuration at the end of the simulation, making it suitable for consecutive maneuvers.

Summary: This article investigates the difficult issue of fixed-time constrained attitude control for a flexible spacecraft under the influence of system uncertainties, environmental disturbance, and abrupt actuator faults. The proposed control framework presents an observer to reconstruct the uncertain dynamics within a fixed time and achieves specific performance specifications by constraining the sliding manifold. The distinctive feature of this control framework is that the settling time of the closed-loop system is finite and explicitly expressed as two tunable gains even when abrupt actuator faults happen.

Summary: This article presents an anti-unwinding attitude maneuver control method for rigid spacecraft, which ensures unwinding-free performance by designing a novel switching function and introducing a dynamic parameter before reaching the switching surface. Additionally, a boundary layer is introduced to avoid chattering phenomenon in the control system.

Summary: The variable shape function allows for attitude and orbit control by actively changing the shape of a spacecraft in orbit. In order to demonstrate this function, the HIBARI satellite was developed with drivable solar array paddles and successfully showcased the world's first in-orbit variable shape attitude control in FY2021. The study compares the behavior of the paddle drive on the ground and in orbit to evaluate its performance, and also uses attitude change angle data from the paddle drive in orbit for comparison and evaluation of control performance.

Summary: This study compares a filament-based free wake panel method to experimental and validated numerical data in order to simulate propeller slipstreams and their interaction with aircraft components. The results show that the free wake panel method is able to successfully capture the slipstream deformation and shearing, making it a useful tool for propeller-wing interaction in preliminary aircraft design.
