“…Note that, the hard-limited saturation model (17) is not smooth at the value |𝜏 i | = 𝜏 i max and thus often complicates the controller design and stability analysis. Besides, the constraint given by a constant 𝜏 i max may not be suitable sometimes since the wear of actuators would change the maximum allowable force.…”

“…As illustrated in Figure 3 and Lemma 5, the hard-limited saturation behavior could be well matched with the dead zone-based model, provided that 𝜌 (𝛽) is properly selected. With this advantage in mind, in this article, we regard the constraint (17) imposed on control inputs as unknowns, that is, 𝜏 i max is unavailable. Then, the dead zone-based model (19) and ( 20) is utilized to approximate such a behavior, leaving two unknown positive variables c i and d i .…”

“…13,14 Consequently, perturbations involving external and internal perturbations must be the concerned primarily when it comes to the factors that prevent the control schemes from achieving high accuracy and strong robustness. In this setting, advanced methods such as neural networks (NNs), [15][16][17][18] fuzzy logic systems, 19 and observation mechanism 20,21 have been deeply researched. The main feature of these approaches lies in their reachability to adjust system's performance according to the variations of external environment.…”

This article tackles the finite-time global trajectory tracking control problem of the autonomous underwater vehicle (AUV) in presence of input saturation constraints, actuator faults, unknown dynamics, and external disturbances. First, we describe the orientation of the AUV by rotation matrix instead of classical Euler angle or unit quaternion such that the AUV's dynamics could be globally formulated without singularity and unwinding phenomenon. After that, a smooth dead zone-based model is introduced here to linearize the actuator model, leaving that the adaptive laws could be suitable for the solution of input saturation and actuator faults. Considering that the difficulty of model dynamic acquirement, together with the complicity of rotation-matrix-based representation, would trouble deployment of the controller. The minimum learning parameter technology is thereby utilized to approximated the dynamic nonlinearity of the AUV. On the basis of these, a rotation-matrix-based sliding mode control scheme is technically proposed. It is proved that the tracking errors can be stabilized to a small neighborhood of origin within a settling time. Finally, several set numerical experiments are conducted to assess the effectiveness and show the advantages of the proposed control scheme.

A satellite mission instruction generation algorithm based on a flexible weighted directed graph has been proposed. This algorithm can sort the instruction into sequence according to the instruction execution relationship with constraints, which can promote satellite operation performance of the ground station. Concepts like flexible edge, flexible zone, and implement zone were introduced, and the flexible weighted directed graph (FWDG) model was proposed. Based on this model, the satellite instruction sequence generation algorithm was designed. After practice and research, the result showed that according to the new algorithm, the instruction sequence can be consistent with all implement zones, consequently guaranteeing the correctness of the sequence.

In this article, the attitude tracking problem for rigid spacecraft subject to external disturbance, inertia uncertainties, and actuator faults is investigated. A novel continuous control strategy is proposed to guarantee that the attitude tracking errors converge with desired performance before an appointed time. In addition, the proposed control law can enable the closed‐loop system to be unwinding‐free. For the purpose, a modified appointed‐time performance function (APF) is used to construct a disturbance observer‐based adaptive attitude control law based on the special orthogonal group (SO(3)). With the aid of the modified APFs, desired performance metrics, including transient and steady‐state performance, on the attitude tracking error can be specified in advance without the requirement for initial values of the tracking system to avoid singularity. By resorting to error transformation and backstepping technique, the control design process is simplified and a few control gains are involved in the proposed control law. Rigorous stability analysis based on the Lyapunov theory is provided to prove the appointed‐time stability of the attitude tracking error as well as the boundedness of all signals in the closed‐loop system despite external disturbance, inertia uncertainties, and actuator faults. Finally, numerical simulations are conducted to support the analysis.
