“…This kind of method has poor adaptability for different constraints, and some tracking performance is sacrificed. In recent years, some high-performance control strategies have been proposed for dynamic and steady-state performance of several kinds of state constrained systems [12][13][14][15][16][17][18][19] and for spacecraft systems. [20][21][22][23][24][25][26][27] This article focuses on designing a method of constraint control to solve the position tracking control problem for quad-rotor system with velocity constrains.…”

This article mainly considers the problem of trajectory tracking control problem of quad-rotor system with velocity constrain under the consideration of safety. A model-based nonlinear controller is proposed which can guarantee not only the asymptotical stability for control system but also the velocity under a safe range. Firstly, based on backstepping design, a position tracking controller with velocity constraint is proposed to ensure that the desired position can be tracked with velocity constrains. At the second step, considering attitude subsystem, an attitude controller is proposed to improve the attitude dynamic response performance. Finally, the validity and superiority of the design has been verified in simulation results.

“…Multimodel adaptive control methods were employed as a fault compensation in literatures [6][7][8]. Literatures [9][10][11] applied neural network to the design of reconfigurable aircraft control in the case of sensors or actuator faults. The fault recognition and faulttolerant control strategies of the near space vehicle are designed base on the adaptive sliding mode control method in reference [12].…”

A comprehensive adaptive compensation control strategy based on feedback linearization design is proposed for multivariable nonlinear systems with uncertain actuator fault and unknown mismatched disturbances. Firstly, the linear dynamic system is obtained through nonlinear feedback linearization, and the dynamic model of the mismatched disturbances as well as its relevance to the nonlinear system is given. The effect of disturbances on the system output is suppressed with the basic controller of the linearized system. Then, a direct adaptive controller is developed for the multiple uncertain actuator faults. Finally, an integrated algorithm based on adaptive weighted fusion could provide an effective compensation for the effect of multiple uncertain faults and mismatched disturbances. Thus, the stability and asymptotic tracking performance of the closed-loop system are ensured. The feasibility and performance of the proposed control strategy are validated by the numerical simulation results.

“…The disturbance observer, which is famous due to its precise estimation for disturbances, has also been widely researched in aerospace engineering [20]- [25]. In [20], the robustness of the spacecraft attitude control system is significantly enhanced by resorting to a specially designed disturbance observer, which can effectively estimate the external disturbance.…”

“…As a further technological extension, two disturbance observers have been established in [17] and [21] such that the formation task could be accomplished under seriously disturbed environment. Considering for the convergence rate, controllers proposed in [21]- [25] possess finite-time stability. Especially, methods in [23] is capable of tackling the actuator fault and the input saturation constraint will not be violated in [24], [25].…”

This paper concerns the control algorithm oriented to nonparallel-ground-track-imaging for agile optical satellite. Firstly, for obtaining the desired trajectory, the mapping relationship between the satellite attitude and the ground stripe is established by using space vector method. According to the mapping function, an attitude adjustment strategy via constant scanning velocity is proposed. Then, considering the exact information of the external disturbance cannot be obtained and the input saturation problem, a robust anti-saturation tracking controller is designed via fixed-time disturbance observer and integral sliding mode. Finally, the effectiveness of the proposed control algorithm is illustrated by numerical simulation. INDEX TERMS Agile optical satellite, nonparallel-ground-track-imaging, integral sliding mode, disturbance observer, input saturation.
