“…In practice, the communication connection of multiquadrotor aircraft system depends on the perceptual range of each quadrotor, but the perception and communication capabilities of each quadrotor aircraft are usually limited. Therefore, the connectivity of the communication topology network cannot be guaranteed at a long distance, which drives us to solve the problem of connectivity preservation . Connectivity preservation is also widely used in multirobot communication .…”

Summary In this article, we investigate the formation control problem of multiquadrotor aircraft system subject to connectivity preservation and collision avoidance. First, based on the backstepping design method, a novel formation control algorithm is developed to enable multiquadrotor aircraft to move along the desired trajectory while becoming the predefined formation pattern. Meanwhile, the connectivity of the communication network is maintained and the collision among multiquadrotor is avoided. Second, for each quadrotor's desired attitude obtained by the formation controller, an improved finite‐time attitude tracking law is designed to guarantee that the desired attitude can be tracked by the real attitude in a fast finite time. Finally, a numerical example is given to demonstrate the effectiveness of the proposed algorithms.

“…ough there are many results on FdTC, the preserving connectivity between agents communicating with each other is seldom taken into account. However, in practice, the communication ability of multiple agents is usually limited, so it is very important to ensure that the agents communicate with each other within a limited communication radius [29][30][31][32]. In addition, for some complex systems, the Lipschitz condition is hard to satisfy.…”

“…Hong et al [31] studied the finitetime consensus problem for second-order nonlinear MASs under communication constraints, and the interaction patterns can be preserved for the system with the objection of disturbance rejection, but the display estimation of convergence time is not given. Hong et al [32] studied fixedtime connectivity-preserving distributed average tracking for first-order MASs without considering the interference and the nonlinear terms. Zuo et al [33] studied the FdTC for MASs over directed and switching interaction topology.…”

“…However, as far as we know, there are few results related to the FdTTC of MASs with the disturbance and general nonlinearity under the limited communication radius between neighbor agents. Hence, inspired by [27][28][29][30][31][32][33][34], this work studies the FdTTC of the first-order leader following MASs with disturbances and general nonlinearities. Based on the integral sliding surface, a new control protocol is designed.…”

is text studies the fixed-time tracking consensus for nonlinear multiagent systems with disturbances. To make the fixed-time tracking consensus, the distributed control protocol based on the integral sliding mode control is proposed; meanwhile, the adjacent followers can be maintained in a limited sensing range. By using the nonsmooth analysis method, sufficient conditions for the fixed-time consensus together with the upper and lower bounds of convergence time are obtained. An example is given to illustrate the potential correctness of the main results.

This paper studies a distributed average tracking problem for a class of networked agents subject to heterogeneous unknown nonlinearities. The object is to design distributed protocols so as to drive these dynamic agents cooperatively tracking the average of multiple unknown signals. First, an initialize‐free robust algorithm is designed for each agent incorporating a local filter, a neural network (NN) compensator, and state‐dependent coupling gains with its neighbors. Here the filter is crucial for seeking the average of multiple references signals and is necessary due to the existence of uncertainties in the agents' dynamics. Then, by using adaption schemes, the algorithm is extended to a dynamic version releasing the requirement of certain global information such as the eigenvalues of the network Laplacian and the NN approximation errors. Both algorithms are rigorously proved to guarantee asymptotical average tracking with the help of well‐designed Lyapunov candidates. Finally, two illustrative examples are provided to validate the theoretical results.
