Summary: This paper focuses on the problem of adaptive fixed-time quantized fault-tolerant attitude tracking for hypersonic reentry vehicles (HRV). The paper proposes a control scheme that can handle nonlinearities, system uncertainties, and actuator faults of the HRV. The proposed scheme includes a disturbance observer and a sliding mode controller, which can achieve fixed-time convergence and reduce communication load. The effectiveness of the proposed scheme is demonstrated through numerical simulations.

Summary: This article investigates the modeling and fault-tolerant control design for a class of flexible air-breathing hypersonic vehicles with actuator faults. The fuselage's shear deformation is considered, and an ODEs-PDEs coupled model is established. A feedback control and an adaptive FTC method are proposed to ensure flight stability and suppress system vibrations. The closed-loop system's stability is analyzed using the Lyapunov direct method, and an algorithm is provided for determining the control gains. Numerical simulation results demonstrate that the proposed controller efficiently stabilizes flight states and suppresses fuselage vibration.

Summary: This paper investigates the event-triggered adaptive control problem for air-breathing hypersonic vehicles (AHVs) subject to physical actuator nonlinearities. In contrast with abundant AHV control strategies belonging to the traditional sample-data framework, the presented adaptive control works with an event-triggered mechanism, which naturally reduces the executing frequency of scramjet fuel-to-air equivalency ratio (FER) and aerodynamic control surface (ACS). Theoretical analysis indicates the guaranteed closed-loop stability and tracking performance while excluding the undesired Zeno behavior. Simulations validate the effectiveness of the proposed event-triggered adaptive control.

Summary: This paper discusses the design of prescribed performance fuzzy back-stepping tracking control for a flexible air-breathing hypersonic vehicle with actuator constraints. Fuzzy logic systems are used to approximate the uncertainty of each subsystem, and a sliding mode differentiator is introduced to avoid the explosion of differentiation term. A prescribed performance function is utilized to improve control performance, and novel auxiliary systems are explored to handle input saturation. Fuzzy backstep control has advantages in system robustness, control accuracy, and real-time performance, as demonstrated by reference trajectory tracking simulations.

Summary: The aim of this article is to develop new second-order fixed-time sliding mode controllers capable of handling mismatched disturbances. Unlike what is commonly done in the literature, the proposed sliding-mode control strategy does not rely on disturbance observers due to the robustness properties of the sliding surface. Moreover, the results are utilized to define a new fixed-time differentiator.

Summary: This paper presents a model-free finite-time terminal sliding mode control scheme for uncertain robot systems, utilizing a time delay estimation (TDE) technique to estimate the system's mathematical model and designing a novel adaptive sliding mode observer to compensate estimation errors. The scheme also includes the design of a nonsingular fast terminal sliding surface to accelerate convergence rate and the use of a boundary layer technique to attenuate chattering phenomenon. Simulation and experimental studies using Rethink Sawyer Robot validate the effectiveness of the proposed scheme, with both observer and controller stability strictly proven in the Lyapunov framework.

Summary: This article proposes an output-feedback fixed-time trajectory tracking control methodology for hypersonic flight vehicles. The most distinguishing feature of this method is that it avoids using conventional recursive design methods and does not rely on full-state availability. By adopting an asymmetric integral barrier Lyapunov function and utilizing the cascaded property, the original constrained system is transformed to an unconstrained one, simplifying the control design and stability analysis.

Summary: This paper presents a finite-time extended, state-observer-based, fixed-time backstepping control algorithm for hypersonic flight vehicles. Two novel finite-time extended state observers are introduced to compensate for the negative effects of disturbances. The use of hyperbolic sine tracking differentiators alleviates computational burden and a fixed-time backstepping attitude controller guarantees tracking errors to converge in a fixed time. Simulation results demonstrate that the proposed controller outperforms other controllers in terms of tracking precision and convergence rate, showing robustness in simulations involving disturbances.
