“…There exists some small time interval T o containing t i e i1 will monotonically pass through zero. Therefore, (40) holds almost everywhere and the observer will converge to the equilibrium point (e i1 = 0, e i2 = 0) in finite time.…”

“…However, we cannot ignore the weak robustness and ''explosion of complexity'' of conventional BC. To enhance the robustness of controller, many disturbance observer (DOB) based techniques were investigated, such as fuzzy-based observer [12], [14], nonlinear disturbance observer [26], [40], [41], super twisting algorithm based observer [29], [30], extend state observer (ESO) [42], [43], etc. Li and Li [12] utilized a novel fuzzy-based approximator to estimate the total uncertainties of velocity subsystem and altitude system.…”

This paper investigates the velocity and altitude tracking control problem for air-breathing hypersonic vehicle (AHV) under external disturbances and uncertainties. An improved smooth supertwisting based disturbance observer (SSTDOB) is proposed to estimate the unknown external disturbances. With the assistance of SSTDOB, an effective fixed-time sliding mode backstepping control (FSMBC) is designed to guarantee the tracking errors converge to a small neighbor of the origin. Meanwhile, a fixedtime tracking differentiator (FTD) is employed to estimate the virtual control inputs, which can eliminate the differential explosion problem. The overall stability of the closed-loop system is analyzed by utilizing Lyapunov stability theory. Simulation results demonstrate the effectiveness of the composite method.

“…e speed control effect of the diesel engine is affected strongly by the inherently unstable and unpredictable external load disturbances; therefore, the active disturbance rejection control has attracted much attention due to its excellent disturbance resistance [12][13][14]. In the theory of ADRC, both inherently unstable and unpredictable external load disturbances are treated as a "total disturbance," which is expanded to a new state of the system and then estimated and compensated by the extended state observer (ESO) [15][16][17]. Due to its excellent antidisturbance ability, ADRC has been widely used in industrial applications.…”

In this paper, in order to handle the nonlinear system and the sophisticated disturbance in the marine engine, a finite-time convergence control method is proposed for the diesel engine rotating speed control. First, the mean value model is established for the diesel engine, which can represent response of engine fuel injection to engine speed. Then, in order to deal with parameter perturbation and load disturbance of the marine diesel engine, a finite-time convergence active disturbance rejection control (ADRC) is proposed. At the last, simulation experiments are conducted to verify the effectiveness of the proposed controller under the different load disturbances for the 7RT-Flex60C marine diesel engine. The simulation results demonstrate that the proposed control scheme has better control effect and stronger anti-interference ability than the linear ADRC.

Nonsingular fixed‐time fault‐tolerant attitude control for tailless flying wing aircraft with time‐varying flight envelope constraints

This article investigates the fault-tolerant attitude control problem for the tailless flying wing aircraft subject to time-varying flight envelope constraints in the presence of the matched/mismatched disturbance, uncertain parameters, and time-varying actuator failures. To handle these problems and improve the convergence rate of the attitude control system, a nonsingular fixed-time convergent robust fault-tolerant control methodology is proposed. First, the time-varying barrier Lyapunov functions is introduced to confine the flight envelope within the predefined time-varying compact set while ensuring the transient performance of the attitude tracking error. Subsequently, the fixed-time sliding mode observer is designed to compensate for the matched/mismatched disturbance, uncertainties, and time-varying actuator failures, meanwhile, by introducing an intermediate control law in the attitude controller, the singularity problem is avoided without utilizing any filters or continuous and differentiable piecewise functions. Further, it has been analytically proved that all signals of the closed-loop system are bounded and converge to the residual set around the origin in a fixed time. Finally, simulations are conducted to illustrate the superiorities of the proposed scheme.
