“…The dynamics of the ith follower (1) is in a non-affine form, and it is more general compared with the plant in [44]. In fact, the dynamics of the ith follower (1) represent many practical systems, for instance, robotic manipulators [45], hypersonic flight vehicles [46] and marine surface vessels [47]. Consequently, the control strategy for an MAS with follower (1) is not only for academic improvement but also for these systems in the real world.…”

A fixed-time active disturbance rejection control (FTADRC) consensus tracking strategy is proposed for a class of non-affine nonlinear multi-agent systems with an event-trigger-based communication. Non-affine followers are transformed into affine ones by combining the implicit function theorem with the mean value theorem. A distributed event-triggered estimator is introduced based on its neighbor output information. It is for estimation of a leader’s signal for parts of followers, who are not able to access the leader signal in a direct manner. A distributed FTADRC control strategy is then developed via an event-triggered communication in the framework of backstepping technology. With the help of the fixed-time control, the settling time of an MAS is assignable and independent on initial conditions. Extended state observers and tracking differentiators are employed to compensate unknown dynamics of each follower in real time and estimate derivatives of virtual control laws, respectively. It is proven theoretically that the MAS achieves input-to-state practically stability and the consensus tracking error converges to a neighborhood around the origin in a fixed time. Also, Zeno behavior is excluded. Finally, two examples are performed to illustrate the effectiveness of the proposed strategy.

“…To show the advantage of the FTC designed herein, we compare the consensus tracking error by our FTC with that by a non-fixed-time one. The two strategies are with the same design parameters for the same follower (46). The curves of consensus tracking error with/without FTC strategy in 1st follower are depicted in Fig.…”

This work proposes a fuzzy adaptive design solving the finite-time constrained tracking for hypersonic flight vehicles (HFVs). Actuator dynamics and asymmetric time-varying constraints are considered when solving this problem. The main features of the proposed design lie in: (a) introducing a novel piecewise but differentiable switching control law, with an appropriate design thought to avoid singularity issues typical of finite-time control; (b) handling actuator magnitude, bandwidth, and rate constraints, thanks to the introduction of an auxiliary compensating system counteracting the adverse effects caused by actuator physical constraints, while guaranteeing the closed-loop stability; (c) handling asymmetric time-varying state constraints, thanks to the introduction of tan-type barrier Lyapunov functions (BLFs) working for both constrained and unconstrained scenarios. Comparative simulation results illustrate the effectiveness of the proposed strategy over existing methods for HFVs in terms of convergence, smoothness, actuator performance, and constraints satisfaction.

“…This challenge would involve many improvements in several disciplines. It is widely acknowledged that the field of unmanned aerial vehicles has been much investigated during the last decade, and has attracted the interest of many researchers working in disciplines particularly related to automation [1][2][3][4][5] electronics [6][7][8], mechanics and aerodynamics [9][10][11]. Drones or UAVs are unmanned flying vehicles capable of carrying out a mission in autonomy or semi-autonomous.…”

The aeronautics studies and particularly the development of drones represent an important field, in which there is a very large number of research and studies.This article aims to present an experimental aerodynamic study of an autonomous surveillance unmanned aerial vehicle (UAV) that is capable of combining the advantages of both categories, namely the fixed-wing drones and the rotary-wing drones. To achieve this objective, a wind tunnel was used to study the flow around this drone in order to better understand the aerodynamic phenomena and to obtain some initial estimates of the lift, drag and moment coefficients, at three different Reynolds numbers of 4.02×104, 6.03×104 and 8.04×104, and for different angles of attack, from [−45°, +45°] with step of 1°.The experimental results obtained in this work show an casi-symetrical variation bertwen the negatif and positif incidence angles of the lift coeffecient, wiche indicate that the heliplane can fly in an inverted position, whatever the angle of incidence. Moreover, the minimum mean value of drag coeffecient according 1° incidence angle is 0.0478 then the drag due to geometry and pitching moment can never be canceled.
