“…On the other hand, except for stabilization, transient performance is widely considered to be a very significant index for hypersonic flight control systems. Prescribed performance control (PPC) [9], [22] has been shown to efficiently guarantee transient performance. The key point of PPC is to devise performance functions which are used to impose funnel constraints on tracking errors.…”

This article investigates the robust adaptive control system design for the longitudinal dynamics of a flexible air-breathing hypersonic vehicle (FAHV) subject to parametric uncertainties and control input constraints. A combination of back-stepping and nonlinear disturbance observer (NDO) is utilized for exploiting an adaptive output-feedback controller to provide robust tracking of velocity and altitude reference trajectories in the presence of flexible effects and system uncertainties. The dynamic surface control is introduced to solve the problem of "explosion of terms." A new NDO is developed to guarantee the proposed controller's disturbance attenuation ability and to performance robustness against uncertain aerodynamic coefficients. To deal with the problem of actuator saturation, a novel auxiliary system is exploited to compensate the desired control laws.The stability of the presented NDO and controller is analyzed. Simulation results are given to demonstrate the effectiveness of the presented control strategy.

“…The problem has been addressed in the works of Bechlioulis and Rovithakis 13,14 and Theodorakopoulos and Rovithakis 15 by means of prescribed performance control (PPC) techniques, which permit the designer to prescribe the transient and steady-state performance of the closed-loop system, regarding the overshoot, the convergence rate, and the steady-state error. The concept of PPC was further extended to flight control systems, [16][17][18][19] vessel control systems, 20 and output-feedback control systems [21][22][23] successfully. Even so, it is noteworthy that the aforementioned PPC approaches 13,14,[21][22][23] require the a priori known control direction (ie, the sign of the control coefficient).…”

“…2. The method is structurally simple and functionally effective in the sense that no approximating structures, such as neuro/fuzzy systems used in other works, 17,18,23,[28][29][30][31][32]34 are used, despite unknown nonlinearities. 3.…”

Summary This paper focuses on the output‐feedback tracking control problem for a class of nonlinear systems with both unknown nonlinearities and unknown control directions. An adaptive prescribed performance controller combined with a Nussbaum gain and a dividing line is proposed to solve the problem. Compared with the existing results, (i) both the convergence rate and the ultimate bound of the tracking error can be prescribed; (ii) no approximating structures such as neuro/fuzzy systems are used, regardless of unknown nonlinear functions; and (iii) the computational burden is alleviated in the sense that the iterative calculation of command derivatives is avoided and the number of online learning parameters is largely reduced. Simulation results are given to further illustrate the established theoretical findings.
