“…Also based on observer technology, unavailable system parameters are observed for spacecraft control systems, involving attitude control [19] , rendezvous control [20][21] and formation coordinated control [22] . In contrast to these forgoing literatures, the bound of the lumped uncertainties is handled via constructing adaptive update laws in [23]. Obviously, the estimation and tracking for an uncertain scalar parameter is relatively simple, whereas complex variables such as matrices are difficult to deal with.…”

This paper investigates the problem of rotation matrix-based attitude synchronization and tracking control for spacecraft formation flying exposed to external disturbance and unknown inertial matrix. For the purpose of ensuring finite-time convergence for attitude tracking errors, a hyperbolic tangent function-based sliding mode surface is designed. Based on the sliding mode variable, an adaptive law is proposed to estimate the upper bound of unknown disturbance and radial basis function is employed to approximate unknown system dynamics. The minimum learning parameter algorithm is adopted to reduce the computational burden. It is demonstrated by Lyapunov-based analysis that the sliding mode surface and estimating errors will possess finite-time stability under the presented controller. Finally, results of numerical simulations are exhibited to validate the stability and validity of the proposed controller.

Summary In this paper, an adaptive fixed‐time fault‐tolerant control scheme is presented for rigid spacecraft with inertia uncertainties and external disturbances. By using an inverse trigonometric function, a novel double power reaching law is constructed to speed up the state stabilization and reduce the chattering phenomenon simultaneously. Then, an adaptive fixed‐time fault‐tolerant controller is developed for the spacecraft with the actuator faults, such that the fixed‐time convergence of the attitude and angular velocity could be guaranteed, and no prior knowledge on the upper bound of the lumped uncertainties is required anymore in the controller design. Comparative simulations are provided to illustrate the effectiveness and superior performance of the proposed scheme.

“…A hybrid PID attitude control law was developed in [7] to achieve global asymptotic stability in the presence of constant disturbance. In [8], an adaptive backstepping control using barrier Lyapunov function was investigated for attitude tracking of uncertain spacecraft system to solve the problem of input and output constraints. However, these attitude control laws can only achieve asymptotic stability or convergence.…”

In this paper, an adaptive nonsingular terminal sliding mode control (ANTSMC) is investigated for attitude tracking of spacecraft with actuator faults. First, a nonsingular fast terminal sliding mode surface is designed to avoid the singularity. Finite-time attitude control is developed using the nonsingular terminal sliding mode technique, which can make the attitude and angular velocity tracking errors converge to zero in finite time in the presence of uncertainties and external disturbances. Second, the total uncertainty is deduced to be bounded. The adaptive laws are incorporated to develop the ANTSMC, removing the restriction on the upper bound of the lumped uncertainty. The finite-time convergence of the closed-loop system with ANTSMC is proved using the Lyapunov stability theory. Finally, the simulation results are presented to demonstrate the performance of the proposed controllers. INDEX TERMS Spacecraft, nonsingular terminal sliding mode, adaptive, finite time, attitude control, actuator faults.
