In this paper, an appointed time active vibration suppression controller is studied for flexible satellite with piezoelectric actuators. Firstly, a piecewise sliding mode controller with the appointed time is designed to guarantee that the attitude error converges at the appointed time. The convergence time of the model can be set with a prior parameter. Secondly, a modal observer is used to estimate the vibration of the flexible elastic modal, and an active vibration suppression controller is designed to converge at a predefined time. The stability of the two controllers is demonstrated by a Lyapunov theory. The Simulink simulation framework is eventually established, and the numerical simulation results of various data demonstrate the appointed time convergence of the proposed controller. Compared with adaptive sliding mode and nonsingular terminal sliding mode, the controller can achieve higher precision control with less energy consumption.

“…[19][20][21] By several remarkable advantages, DO was perceived as an effective technique for disturbance estimation. [22][23][24] Hosseinabadi et al 25 proposed a DObased terminal sliding-mode control (TSMC) scheme to guarantee the finite-time stability of the doubleintegrator system. Based on that finite-time scheme, an improved fixed-time DO is designed to deal with the time delay problem between the two chaotic subsystems.…”

This article proposes a fixed-time fuzzy disturbance observer–based adaptive integral sliding-mode spacecraft control scheme with consideration of input uncertainties and unknown nonlinearities. First, for the purpose of satisfying the time-varying output constraints and simplifying the computational process, an error transformation function is employed to convert the constrained spacecraft system into an unconstrained one. Second, to ensure superior transient-state performance, an improved sliding manifold integrated with a nonlinear function is designed. Then, for accurately estimating the external disturbances, a fixed-time fuzzy disturbance observer is proposed. Furthermore, the unknown nonlinearities and the input uncertainties are handled by several adaptive laws. The simulation results are presented to verify the superiority and effectiveness of the proposed fixed-time fuzzy disturbance observer–based adaptive integral sliding-mode control scheme.

“…Considering the control input constraint of a spacecraft, the homogeneous theory based saturated finite‐time control law was reported to ensure the attitude stabilization in [11]. In [12], the observer technology was introduced to address the uncertainty and flexible vibration of a flexible aircraft. Based on the observer information and the Lyapunov controller design method, the fast attitude maneuver of a flexible spacecraft can be achieved.…”

This paper investigates the appointed‐time attitude stabilization problem of a rigid spacecraft under disturbance and parametric uncertainty. A continuous appointed‐time sliding mode disturbance observer is presented to observe the synthetical disturbance term. To circumvent the singularity problem in terminal sliding mode control, a new nonsingular appointed‐time sliding mode surface is designed by employing the concept of switching control. Based on the observation information deriving from the proposed disturbance observer, an observer‐based nonsingular sliding mode control scheme is developed to stabilize the attitude control system within appointed time which is given by the user. And also, the undesired control chattering phenomenon can be attenuated. The appointed‐time stability of the controlled attitude system is proved by the Lyapunov criteria. The simulation results show that the proposed attitude stabilization control scheme is valid.
