“…The difficulty in robust stabilization about closed-loop system with uncertainties and exogenous random disturbances was solved when the average anisotropy is known [6]. In [7,8] , the spacecraft attitude control problem with measurement error was investigated, and a robust anti-disturbance control law and a noise reduction EDO build the foundation for an augmented disturbance representation were designed to convert the high stability attitude stabilization into reality [7,8]. A robust nonlinear controller was offered to redistribute a virtual control signal to the rest actuators when the faults happened [9,10].…”

“…However, in many existing systems, a realization of high gain DOBs is challenging due to the mechanical limit of the control input and observation noise. Furthermore, the actuator's service life may be shortened due to the chattering motion by estimation noise from the DOBs [8]. Conventional DOBs have a trade-off between disturbance suppression performance and noise sensitivity [4] under noisy environments.…”

“…Thus the measurement uncertainty is also involved in the attitude controller design of combined spacecraft. In paper [25] and [26], the attitude control problem with measurement error was investigated, and a noise reduction extended disturbance observer and a finite-time integral sliding mode disturbance observer were used to estimate the integrated uncertainties, respectively. In this paper, two disturbance-observers-based dynamic surface control method is used to develop the virtual attitude control.…”
