“…These methods are highly effective in handling unknown terms because of their remarkable capability to approximate complex functions [6][7][8]. Adaptive backstepping control protocols incorporating FLSs have been widely and fruitfully applied in different axisymmetric systems, such as satellite clusters and unmanned aerial vehicles [9,10]. In [9], they devised an adaptive fuzzy backstepping control approach to tackle the attitude stabilization problem under consideration.…”

This article concentrates on the problem of fixed-time tracking control for a certain class of nonlinear systems with unmodeled dynamics. Unmodeled dynamics are prevalent in practical engineering systems, such as axially symmetric systems like robotic arms, spacecraft, and missiles. In this paper, the fuzzy-logic systems (FLSs) are implemented to address the challenge of accurately approximating the unknown nonlinear terms that arise during the derived control algorithm process. By employing fixed-time command filters (FTCF), the “explosion of complexity” issues encountered in traditional backstepping methods will be effectively resolved. Moreover, error compensation mechanisms are derived to effectively mitigate the filtering errors that may arise from the FTCFs. The computational burden associated with FLSs is reduced through the utilization of the weight vector estimation method based on the maximal norm and an adaptive approach. A fixed-time adaptive fuzzy tracking controller is developed within the backstepping control framework to ensure the boundedness of all signals and achieve fixed-time convergence of the tracking error for the controlled system. Illustrative examples are conducted to illustrate the viability of the derived controller.

“…In Ref. 22, the dynamic quantizer is used to quantize the signal measured by the sensor, and the quantization parameter can be adjusted online. Note that most existing quantization control schemes are the result of asymptotic stability and few literature consider the predefined-time attitude control (PTAC) with quantization.…”

This article addresses the problem of predefined-time attitude takeover control (PTATC) of spacecraft by using cellular satellites with limited inter-satellite communication capacity. To reduce the communication burden in the wireless networks, a dynamic uniform quantizer is employed to quantize the attitude signals and angular velocity signals measured by the sensor cellular satellites (SCSs). Besides, a static uniform quantizer is used to quantize the control torque signal generated by the controller cellular satellite (CCS). A predefined-time quantized attitude control law is designed, which can compensate for the quantization error. The proposed PTATC scheme can reduce the communication burden among the cellular satellites and achieve the desired angular velocity and attitude of the combined spacecraft within the predefined-time on the premise of ensuring the system performance. Under the proposed control law, all the signals in the closed-loop system can converge into a bounded region within a predefined-time. Finally, numerical simulations are presented to illustrate the effectiveness of the proposed scheme.

“…To solve the problem of actuator failure, Jiang et al [20] proposed an adaptive attitude controller using a redundancy actuator control strategy to achieve high precision of the attitude, but the failure processing method can still be improved. Liu et al [21] proposed an adaptive fuzzy backstepping control scheme to solve the fault-tolerant attitude control of flexible spacecraft under the digital communication channel through sensor signals and controller indicators. This strategy can guarantee the superiority and effectiveness of the spacecraft system in the presence of inertial uncertainty, external interference, actuator saturation, and other faults.…”

This paper focuses on the attitude control problems of spacecraft with external interference and platform actuator failure. The Lagrange method is used to establish dynamic models of complex spacecraft composed of rotating appendages and platform, and the quaternion is used to describe spacecraft attitude kinematics. Second, a fault-tolerant control algorithm that combined adaptive fuzzy control with finite time sliding mode is proposed for the spacecraft platform, and fixed-time control schemes are proposed for rotating parts to achieve stable rotation of the spacecraft components relative to the platform. Finally, a numerical simulation is performed to verify the superiority and effectiveness of the proposed control laws, and comparisons with other control methods are presented.
