“…Secondly, SFSs describe a variety of practical nonlinear systems. Such a fact has been verified by a great deal of applications, including, but certainly not limited to, circuit system (Khalil, 2002), pendulum systems (Jiang & Nijmeijer, 1997;Khalil, 2002;Yang et al, 2004), robotic systems (Dawson et al, 1994;Ferrara & Giacomini, 2000;Jiang & Nijmeijer, 1997;Khalil, 2002;Riccardo & Tomei, 1995;Yang et al, 2004), missile and satellite control systems (Farrell et al, 2005;Kim et al, 2004;Sun et al, 2017), and ship fin roll stabilisation systems (Yang et al, 2004).…”

An advantage of a high-order fully-actuated (HOFA) system is that there exists a controller such that a constant linear closed-loop system with an arbitrarily assignable eigenstructure can be obtained. In this paper, a generalised form of the conventional first-order strict-feedback systems (SFSs) is firstly proposed, and a recursive solution is proposed to convert equivalently the generalised SFS into a HOFA model. Then the second-and high-order SFSs are defined and their equivalent HOFA models are also derived. It is further shown that, under certain common conditions, the recursive solutions for converting the generalised SFSs into HOFA models can be rearranged into direct analytical explicit solutions. Such a high-order system approach is more direct and simpler than the first-order system approach since it avoids the process of converting firstly these second-and high-order SFSs into firstorder ones for control, and can finally produce a constant linear closed-loop system. Particularly, it is more effective than the well-known method of backstepping since, for the generalised complicated SFSs with more subsystems, the method of backstepping may simply be not applicable due to more serious 'differential explosion' problem. Two examples are worked out to demonstrate the effect of the approach.

“…However, this paper focuses on the output constraints problem by using the DSC approach. The considered system is general in that: (i) if

δ_{i} false(x, t false) \equiv 0,

\forall i,

then (1) reduces to the typical strict‐feedback form, therefore, system (1) can include the strict‐feedback systems as special cases; (ii) both parametric uncertainties and general non‐linear function uncertainties as well as unknown input gains are taken into account, the unknown functions could be measurement noise, modelling errors, external disturbances and so on; and (iii) many practical systems can be modelled by or transformed into the semi‐strict feedback system in (1), such as direct current motor driven robotic manipulator system [36, 37], missile autopilot system [38], motor driven pendulum system [39], hydraulic servo system [40, 41] and so on.…”

An adaptive sliding mode control (SMC) algorithm is developed for a missile with highly non-linear aerodynamics. Conventional SMC algorithms have inherent robustness to system model errors, but they often induce chattering of the actuator commands. An adaptive switching gain based on the Lyapunov stability theory is proposed to mitigate the chattering in the steady state. The gain varies with respect to the distance from the sliding surface. The controller with the adaptive switching gain also has robustness to system model errors and unexpected changes in aerodynamic coefficients. A control command generation method using the estimated actuator characteristics is proposed. The proposed method avoids the control performance degradation caused by actuator fault or model disagreement. The effectiveness of the proposed control algorithm is verified through numerical simulations.
