“…Compared with existing distributed observer methods 40,41 that only observe leaders' velocities, the proposed DETO enables each node to acquire its own local reference signal rather than the global states of leaders. Besides, in our results, the positive MIET guaranteed result for the first-order linear multi-agent system 38 is further extended to multiple underactuated SV systems, which is a typical second-order system and possess unknown nonlinear dynamics. With the combination of the DETO and the adaptive local tracking controller (ALTC), the event-triggered affine formation maneuver control for multiple underactuated SV systems becomes a solvable problem.…”

“…Very recently, by introducing internal clock variables, several event-triggered methods with positive MIET guarantees were developed for multiagent systems. 38,39 With this design, the MIET of inter-vessel communications is only determined by control parameters and network connections. By this virtue, the trade-off between the network resource utilization and control performance can easier to be balanced.…”

This article investigates the distributed event‐triggered affine formation maneuver control problem for multiple underactuated surface vessel (USV) systems with positive minimum inter‐event times (MIET). Unlike common formation control methods that only ensure the formation system to keep a fixed geometric shape, the proposed scheme enables multiple USVs maneuver as a group in translation, shearing, rotation, or combinations of them. The proposed control strategy is composed of two parts. First, a distributed event‐triggered observer (DETO) is proposed to observe the time‐varying target formation under the lack of global leaders' information and govern the inter‐vessel communications among the formation group. Besides, the MIET of the designed communication strategy is proved to be strictly positive and computable from formation configurations and control parameters. With these guarantees, the maximum communication frequency can be known in advance. Then, upon the DETO signals, the adaptive local tracking controller is subsequently synthesized for each vessel to realize the target formation track. Rigorous theoretical analysis and simulation results are finally conducted to verify the validness and effectiveness of the proposed algorithm.

This article studies the leader‐following attitude coordination problem of a group of rigid spacecraft subject to communication constraint, disturbances and uncertain control coefficient matrices. A fully distributed adaptive anti‐disturbance attitude coordinated control scheme with event‐triggering mechanism is developed. First, the event‐triggered adaptive distributed observer is designed for each follower to estimate the leader's information without continuous communication requirement. Based on the estimated information, the adaptive anti‐disturbance attitude tracking controller is designed such that asymptotic coordinated tracking can be achieved under additive disturbances and actuators' partial loss of efficiency. The proposed control scheme ensures that all the closed‐loop signals are bounded and the positive lower bound of inter‐event times exists in each subsystem. Simulation results illustrate the effectiveness and flexibility of the proposed control scheme.
