“…This section, drawing inspiration from previous research works [2]- [4], delves into the design of an appropriate observer intended for estimating the modal variables and disturbances in the context of a flexible satellite. To this end, Lemma 1 and Lemma 2 are employed as a pivotal components of the proposed approach:…”

A finite-time observer-based attitude controller is designed for a flexible satellite in the paper titled "Finite-Time Control Algorithm Based on Modal State Observer for Flexible Satellite Attitude Tracking" which referred to as the "original paper" hereafter. Through a comprehensive review of the article, it has become evident that the design of the observer in original paper contains critical errors, rendering the results presented therein invalid. In this corrigendum, we meticulously discuss the identified flaws in the original paper and present the necessary amendments to rectify them. Furthermore, we enhance the finitetime observer proposed in the original paper to not only estimate the effects caused by modal variables but also account for the effects resulting from external disturbances and the inherent uncertainty associated with the moment of inertia of the flexible satellite. The finite-time convergence property of the proposed observer, presented within this corrigendum, is assured through the utilization of the Lyapunov approach. By employing the proposed observer outlined in this corrigendum, the validity of the remaining components highlighted in the original paper is preserved, providing an accurate framework for further research and practical applications.INDEX TERMS Attitude tracking, finite-time control, finite-time observer, flexible system.

“…A tremendous amount of research efforts has been spent on the development and test of advanced control approaches for unmanned vehicles, such as sliding mode control [1][2][3][4][5][6][7][8], model predictive control [9][10][11][12], backstepping control [13][14][15][16][17], active disturbance rejection control [18][19][20][21], adaptive control [22][23][24][25] and fixed-time control [26][27][28]. Among them, sliding mode control has shown excellent robustness to external disturbances and model uncertainties, and it is convenient in the design and debugging of control parameters.…”

This paper proposes a trajectory tracking control scheme consisting of a fast finite-time super-twisting sliding mode control (FSTSMC) approach and an extended state higher-order sliding mode observer (ESHSMO) for unmanned underwater vehicles (UUVs) with external disturbances and model uncertainties. Firstly, an extended state higher-order sliding mode observer with the finite-time convergence is designed based on the higher-order sliding mode technique and the extended state observer technique. Next, on the basis of disturbances and model uncertainties observation, a fast finite-time super-twisting sliding mode control approach is proposed, and the finite time stabilization property of the tracking errors is proved by Lyapunov theory. Finally, through numerical simulation and experiment in a water pool, it has been verified that the proposed control scheme has achieved the high control precision, the smaller chattering, the disturbance compensation and the fast finite-time convergence in UUV trajectory tracking.

“…Despite the low-complexity structure of the controllers constructed from the FC method, no asymptotic tracking is pursued, but the constraint on the system output will be satisfied over the whole time interval [34]. Although there are numerous constrained attitude controls using the PPC approach [35][36][37][38][39][40], there is no FC-based constrained attitude control for spacecraft and it is still an open problem.…”

Constrained Nonsingular Terminal Sliding Mode Attitude Control for Spacecraft: A Funnel Control Approach

This paper presents an adaptive constrained attitude control for uncertain spacecraft. Inspired by the concept of nonsingular terminal sliding mode control and funnel control for nonlinear systems, a novel adaptive attitude control is introduced which contains a time-varying gain to handle the constraints imposed on the spacecraft attitude. Indeed, when the attitude trajectory approaches the boundary of the constraint set, the control effort as well as the time-varying gain will increase in order to preclude the trajectory from intersecting the boundary. Then, it is analytically proved that the system trajectories converge to an arbitrary small region around the origin within a fixed time where the smallest upper bound of the convergence time is determined as an independent parameter in the controller. Further, the proposed control scheme is nonsingular without having to use any piecewise continuous function which simplifies stability analysis. These properties distinguish the proposed control scheme from the existing finite/fixed-time attitude controls. Finally, several simulation results confirm the robustness and performance of the proposed control framework.
