“…Practically, many real and complicated systems have a switched nature, for example networked control systems (Donkers et al, 2011; Wu et al, 2018), continuously stirred tank reactors (Mhaskar et al, 2008; Yazdi and Jahed-Motlagh, 2009), electro-mechanical systems (Leith et al, 2003), electronic power systems (Deaecto et al, 2010; Dijk et al, 1995), vertical and/or short take-off and landing aircraft (Oishi and Tomlin, 1999) and multi-agent systems (Xie et al, 2018). In addition, other examples of typical applications of switched systems in engineering and industrial applications include: air traffic management (Tomlin et al, 1998), underactuated underwater vehicle (Sankaranarayanan et al, 2008), vehicle suspension control (Du et al, 2014), robotic manipulators (Yang et al, 2016), flexible hypersonic vehicle (Zhang et al, 2019a), morphing aircraft (Wang et al, 2019), and low-thrust space tug system (Sun and Zhong, 2018). Generally, because of their hybrid nature, switched systems do not obtain subsystem properties (Zhao et al, 2017).…”

This paper deals with model reference adaptive control for an uncertain switched linear system in the presence of disturbances in the state and control input based on time-dependent switching methods. A novel composite disturbance observer-based adaptive controller with adaptive laws is proposed in a tracking problem of uncertain switched linear system. First, two disturbance observers are proposed to estimate disturbances. Then, a hybrid switched adaptive controller based on state feedback and disturbance observers is designed. Thereafter, based on time-dependent switching signals included dwell-time (DT), average dwell-time (ADT), and the mode-dependent approaches of DT and ADT, a globally uniformly ultimately bounded stability of the closed-loop switched linear system is proved. Finally, the theoretic achievement is applied to a highly manoeuvrable aircraft technology vehicle to demonstrate the significance of the proposed method.

“…In terms of control, the main objective is to reach the specific camber to adapt to the current flight phase. In the current researches, Wang et al investigated the control problem of morphing wings based on switched nonlinear systems and adaptive dynamic programming [7]. The author of [8] systematically studied the control authority of camber morphing flying wings.…”

Flexible skin and continuous deformable control surface are the basic of adaptive wing technology for future aircraft. This paper presents a continuous morphing trailing-edge and its control allocation method for the flying wing Unmanned Aerial Vehicle (UAV). Firstly, we apply the Kriging method to establish the aerodynamic model of the morphing trailing-edge, with the initial sample points generated by the non-uniform optimal Latin Hypercube Sampling (LHS). Then, based on the Kriging model, the multi-objective control allocation problem is converted into a standard optimization form. To solve such problem, we design a Comprehensive Multi-Objective Particle Swarm Optimization (C-MOPSO) algorithm and an improved Hierarchical MOPSO (H-MOPSO) algorithm, in which multiple optimization objectives are prioritized and hierarchically optimized using the PSO algorithm. As for performance analysis, an attitude angle tracking flight control system is established to validate the effectiveness of our proposed control allocation methods. Simulation results show that both the C-MOPSO and H-MOPSO methods have similar performance in attitude angle tracking, while H-MOPSO achieves better multi-objective allocation performance.INDEX TERMS Flying wing UAV, morphing trailing-edge, Kriging aerodynamic modeling, multiobjective control allocation, Particle Swarm Optimization.

“…As a special kind of aircraft, the morphing aircraft can adapt to different flight environments by altering its aerodynamic configurations, which would handle the aircraft design contradictions caused by high speed and low speed conversion [1][2][3][4]. Due to its superior flight performance, morphing aircrafts have attracted an increasing number of the attention from both industry and academy.…”

In this paper, the problem of the back-stepping fault-tolerant control (FTC) based on fixed-time observer is addressed for the morphing aircraft with model uncertainties, external disturbances, and actuator faults. First, the longitudinal dynamics for the morphing process are presented, and the control-oriented models subject to undesired malfunctions are established. Second, the fixed-time observer is designed for offering estimations of compound disturbances, including system uncertainties, disturbance, and malfunction information. Especially, the observer errors could converge to zero by the proposed observer within a settling time, which is independent of the system's initial conditions. Then, a back-stepping FTC strategy based on the observations is proposed for the altitude and velocity subsystem, and the stability of the close loop system would be guaranteed by the proposed controller despite the actuator failures. Furthermore, to eliminate the effects of the "explosion of complexity" of the backstepping method, a modified dynamic surface is applied to compute derivatives of virtual laws. Finally, the numerical simulations verify the effectiveness of the proposed control approach.
