“…The backstepping control method provides a more structured and systematic approach of controller design, relieving the limitations of mismatched items by introducing virtual control, which shows its unique advantages in dealing with mismatched uncertain problems. Therefore, many researchers combine advanced control techniques, such as input-output feedback linearization [4], fuzzy control [5], sliding-mode technique [6], robust technique [7], disturbance observer technique [8,9], etc., within the framework of backstepping control design for handling mismatched uncertainties of the HSVs.…”

This paper develops and validates a modified backstepping control scheme for hypersonic vehicles (HSVs) with uncertain dynamics and angle-of-attack (AOA) constraint, which incorporates a novel finite-time extended state observer (FTESO) and a time-varying barrier Lyapunov function (BLF)-based controller. In order to ensure that observation errors converge before the controller reaches the steady states, the “adding a power integrator” (AAPI) technique is utilized to design the FTESO by transforming the observation problem of the traditional extended state observer (ESO) into a stabilization problem. Combining time-varying constraints and tracking errors to construct the BLF, the backstepping control law that can adapt to large initial tracking errors is derived. Theoretical and comparative simulation results show that the proposed FTESO performs well in terms of speed and accuracy, and AOA is constrained within the prescribed region.

“…25 Then, we need to have the aid of certain effective means to offset the disadvantages produced by disturbances. To improve the accuracy of tracking control, several attempts have been made in the presence of disturbances, for example, H ∞ control, 26 sliding mode control, 27 and disturbance estimation and compensation technology. 1,[28][29][30][31][32][33][34] Among the above-mentioned strategies, disturbance observer (DO) is one of the most effective and popular methods to estimate the unknown disturbances, which has extensively applied in many industrial fields due to its simple structure and extraordinary capability to estimate disturbances, such as robotic manipulator, 32 servo system, 33 and aircraft system.…”

In this paper, a variable-horizon predictive tracking control (VHPTC) scheme based on composite disturbance observer (CDO) is proposed to investigate the attitude tracking problem for an air-breathing hypersonic vehicle (AHV) subject to external matched and mismatched disturbances. An explicit predictive tracking control term with the variable horizon is employed to reduce the online computation and improve the control performance of the AHV system. To comprehensively suppress the negative influences caused by the matched and mismatched disturbances, a CDO is constructed to estimate the unknown disturbances. Moreover, to further guarantee the stability of the closed-loop system affected by the resulting disturbance estimation error, the auxiliary control term is presented. Combining the predictive tracking control term with the variable horizon, the auxiliary control term, and the disturbance compensation control term obtained by CDO, the entire VHPTC law for the AHV system is obtained. Through the Lyapunov analysis, the rigorously exponential stability of the closed-loop system is ensured by the proposed CDO-based VHPTC scheme. The simulation results demonstrate the effectiveness of the presented strategy for the AHV attitude system.

“…Nevertheless, few shortcomings of sliding mode that can be compromised by designers are the chattering phenomenon, and it difficultness in handling miss-match uncertainties [12]. To overcome miss-match uncertainties in the mathematical expression, one may augment back-stepping calculation to the sliding mode approach [13].…”

The appearance of uncertainties and disturbances often effects the characteristics of either linear or nonlinear systems. Plus, the stabilization process may be deteriorated thus incurring a catastrophic effect to the system performance. As such, this manuscript addresses the concept of matching condition for the systems that are suffering from miss-match uncertainties and exogeneous disturbances. The perturbation towards the system at hand is assumed to be known and unbounded. To reach this outcome, uncertainties and their classifications are reviewed thoroughly. The structural matching condition is proposed and tabulated in the proposition 1. Two types of mathematical expressions are presented to distinguish the system with matched uncertainty and the system with miss-matched uncertainty. Lastly, two-dimensional numerical expressions are provided to practice the proposed proposition. The outcome shows that matching condition has the ability to change the system to a design-friendly model for asymptotic stabilization.
