A composite control scheme based on a disturbance observer is presented in this paper to deal with the attitude control problem of flexible spacecraft. Specifically, a sliding mode disturbance observer (SMDO) is developed to attenuate the unmodeled system dynamics, parameter uncertainties, and multiple external disturbances. The key feature of this approach is to relax the assumption imposed on disturbance to be constant or changing at a slow rate, which is a typical assumption in this class of problems involving a disturbance observer. Then, an exclusive adaptive integral sliding mode controller is combined with the SMDO to get the improved closed-loop control performance of the system. The underlying benefit of the proposed control scheme is improved robustness against time-dependent external disturbances and system model uncertainties. The stability analysis of the closed-loop system is provided using Lyapunov’s stability theory. Simulation results are provided to show the effectiveness of the proposed control scheme, especially in comparison with existing results.

“…The second one is based on artificial potential function (APF) method. By introducing the APF into the procedure of controller design, different control schemes have been proposed to guarantee the feasibility of attitude pointing constraints and the convergence of closed-loop system, such as APF-based proportional and derivative (PD) controller [7,3,9], APF-based backsteping controller [7], and APF-based sliding mode controller [23,15]. The angular velocity and input constrains are also considered in [9] by utilizing optimal control method [17,10,8,2,24,11].…”

“…Thus the "unwinding" phenomenon might occur especially when the scalar part of the initial attitude quaternion for regulating control or the initial attitude error quaternion for tracking control is negative, which may cause the problem of unnecessarily large rotations during the spacecraft attitude maneuver [3]. The unwinding phenomenon can be solved by introducing the anti-unwinding potential function [7,3,23] into the process of controller design with known angular velocity.…”

<p style='text-indent:20px;'>An output feedback control law is proposed in this paper for spacecraft attitude reorientation task. Although attitude maneuver has been widely investigated and obtained significant results, it is still challenging when considering attitude pointing constraints and lacking the information of angular velocity. Firstly, potential function is introduced to tackle attitude pointing constraints. Then, by jointly designing sign function and potential function, the anti-unwinding performance can also be achieved. Furthermore, the relevant information of angular velocity is obtained by utilizing first-order passive filter with the attitude error quaternion. Moreover, by properly selecting candidate Lyapunov function, the feasibility of attitude constraints can be rigorously proved under the proposed control law, while the stability of the system can be guaranteed without signal of angular velocity and information of inertia matrix. A numerical example is carried out to demonstrate the effectiveness of the proposed method.</p>

“…Over the last several decades, attitude control of spacecraft has gained much attention in the aerospace industry, since it has vital role in completion of many advanced space missions successfully [1], such as spacecraft rendezvous and docking [2]- [4], on-orbit servicing [5], [6], formation flying [7], [8]. In addition, many control schemes have been employed to solve attitude control problems, such as proportional-derivative control [9], [10], passivity-based control [11], adaptive control [12], [13] and sliding mode control (SMC) [3], [14]- [16]. However, the unpredictable space environment and the spacecraft model uncertainty render great difficulties for attitude controller design.…”

High-Performance Adaptive Attitude Control of Spacecraft With Sliding Mode Disturbance Observer

et al. 2022

A new disturbance observer-based control method is presented in this paper to address the attitude tracking problem of rigid-body spacecraft in the presence of external disturbances and parameter uncertainties. Particularly, a sliding mode disturbance observer (SMDO) is designed. The most important feature of this SMDO is the relaxation of the assumption that external disturbances must be constants or changing at a slow rate, which is a typical assumption required in these classes of problems concerning disturbance observer (DO) design but hard to guarantee from the standpoint of practical engineering. In addition, a special adaptive integral sliding mode controller is combined with the SMDO to ensure system state convergence. The proposed control scheme's primary advantage is the enhanced robustness against system parameter uncertainties and external disturbances. Stringent closed-loop system stability analysis is performed using Lyapunov-based stability theory. Numerical simulations are carried out on nonlinear model of spacecraft to validate the proposed control scheme's efficiency compared to the existing methods in the literature.
