Real-time wildfire perimeter tracking provides situational awareness and enhances decision-making during firefighting. This paper proposes a UAV-based system that integrates real-time data collection (using onboard sensors) into a fire propagation model to provide accurate state information on the wildfire perimeter and improve fire prediction. Firstly, a data fusion scheme is devised to employ available historical data in combination with real-time measurements to provide updated inputs to the fire propagation model. Then the model is used to predict the future fire perimeter and uses these predictions to guide the UAV to track the fire perimeter better. The proposed system is evaluated in extensive simulation experiments, demonstrating its effectiveness for real-time wildfire perimeter propagation tracking.

Manipulation tasks in underwater operations were so far only realizable with large work class remotely operated vehicles (ROV). However, new developments in the field of miniaturized fully-electric multi-joint manipulators are opening up applications for small and medium size ROVs. Despite miniaturization of the manipulators, the manipulator-to-vehicle ratio is not identical to that of large work class ROVs. Coupling effects between manipulator and vehicle must be taken into account to ensure good controller performance of the position and attitude of the vehicle and the tool center point (TCP) of the manipulator. In this paper, the modelling of an underwater manipulator based on an extended Newton-Euler method is presented. The proposed method is applied to a Reach Alpha 5 manipulator and validated by static measurements. Further-more, a method for collision detection between arm parts is presented and applied to the Reach Alpha 5 for workspace analysis.
到目前为止,水下作业中的操作任务只能通过大型工作级远程操作车辆(ROV)来实现。然而,小型化全电动多关节机械手领域的新发展正在为中小型rov开辟应用领域。尽管机械手小型化,但机械手与车辆的比例与大型作业类rov不同。为了保证车辆的位置姿态和机械手的工具中心点(TCP)具有良好的控制器性能,必须考虑机械手与车辆之间的耦合效应。本文提出了一种基于扩展牛顿-欧拉法的水下机械臂建模方法。将该方法应用于Reach Alpha 5机械手上,并通过静态测量进行了验证。此外,提出了一种臂部碰撞检测方法,并将其应用于Reach Alpha 5的工作空间分析。

This paper considers the leader-following consensus control for linear multi-agent systems. Two improved dynamic event-triggered control frameworks are proposed. The first one is based on a moving average approach, whereas the second is a fully-distributed control scheme based on a well-chosen Lyapunov function with rigorous proof of adjustable inter-event time. The proposed methods involve model-based estimation and clock-like auxiliary dynamic variables to increase the inter-event time as long as possible eventually. Compared to the static event-triggered strategy and the existing state-of-the-art dynamic event-triggered mechanism, the proposed approach significantly reduces the communication frequency while still guaranteeing asymptotic convergence. Numerical simulations demonstrate the validity of the proposed theoretical results.

The problem of unknown external disturbances compensation for a class of linear systems with an unmeasured and delayed state is considered. The proposed solution is based on the use of the internal model principle and the extended error adaptation algorithm. It is assumed that the disturbance is the output of an autonomous linear generator with unknown parameters. A special observer is constructed to estimate the disturbance. The proposed approach does not require identification of the disturbance parameters. It is shown that in the presence of any state delay, the control algorithm preserves the stability of the closed-loop system. The performance of the obtained result is confirmed using computer simulation.

Virtual Coupling has been included among the most relevant innovations to be studied in the European Horizon 2020 Shift2Rail Joint Undertaking for increasing the railway lines capacity through the dynamic connection of two or more trains to form a convoy while preserving safety. Within this framework, this paper addresses the virtual coupling control problem for heterogeneous nonlinear uncertain connected high-speed trains. Leveraging the Multi-Agent Systems framework, a novel distributed robust and adaptive PI-like control scheme is proposed to solve the control problem. In order to provide suitable adaptive mechanisms for the control gains, we exploit the Lyapunov theory and Barbalat’s lemma and prove the asymptotic stability for the overall networked control system, as well as the boundedness of these signals. The virtual coupling objective is achieved in a fully-distributed fashion by limiting the amount of time-varying information necessary for the computation of the control action and, hence, saving communication channel bandwidth while reducing the computational burden. Exemplary numerical simulations are given to support the theoretical derivations and to prove the effectiveness of the proposed control strategy in a real driving scenario.
虚拟耦合已被列入欧洲地平线2020 Shift2Rail联合承诺研究的最相关创新之一,旨在通过两列或多列火车的动态连接来提高铁路线的容量,同时保持安全。在此框架下,研究了非均质非线性不确定互联高速列车的虚拟耦合控制问题。利用多智能体系统框架,提出了一种新的分布式鲁棒自适应pi控制方案来解决控制问题。为了给控制增益提供合适的自适应机制,我们利用Lyapunov理论和Barbalat引理,证明了整个网络控制系统的渐近稳定性,以及这些信号的有界性。通过限制计算控制动作所需的时变信息的数量,以完全分布式的方式实现虚拟耦合目标,从而节省通信信道带宽,同时减少计算负担。通过示例性的数值模拟来支持理论推导,并证明了所提出的控制策略在实际驾驶场景中的有效性。

This paper presents control strategies based on time-varying convergent higher order control barrier functions for the coordination of networks of platoons. This network could be modelled by a class of leader-follower multi-agent systems, where the leaders have knowledge on the associated tasks and control the performance of their platoon involved vehicles. The followers are not aware of the tasks, and do not have any control authority to reach them. They follow their platoon leader commands for the task satisfaction. Signal temporal logic (STL) tasks are defined for the platoons coordination. Robust solutions for the task satisfaction, based on the leader’s accessibility to the follower vehicles’ states are suggested. In addition, using the notion of higher order barrier functions, decentralized barrier certificates for each vehicle evolving in a formation dynamic structure are proposed. Our approach finds solutions to guarantee the satisfaction of STL tasks independent of the agents’ initial conditions.

This paper presents the ability of the federated learning concept to create a collaboration between multiple devices using a shared global model, while still keeping data privacy to meet the General Data Protection Regulation (GDPR). In real-world application scenarios, this concept faces problems related to the defense of the global model from possible attacks and the compatibility with non-independent and identically distributed data (non-IID). This paper presents two aggregation algorithms compatible with non-IID data, which use a refined aggregation of the local model, based on their accuracy. Thus, the proposed algorithms can refine the confidence in each client, eliminate intruders and allow a safe aggregation of the global model. Testing scenarios performed for IID and non-IID data illustrate that the proposed algorithms are able to provide faster training and improved robustness against intruders, w.r.t. the well-known federated average algorithm.
本文介绍了联邦学习概念的能力,使用共享的全局模型在多个设备之间创建协作,同时仍然保持数据隐私以满足通用数据保护条例(GDPR)。在真实的应用场景中,这个概念面临着与保护全局模型免受可能的攻击以及与非独立和相同分布的数据(non-IID)的兼容性相关的问题。本文提出了两种适用于非iid数据的聚合算法,在保证精度的基础上,对局部模型进行了精细化的聚合。因此,所提出的算法可以细化对每个客户端的信任,消除入侵者,并允许全局模型的安全聚合。针对IID和非IID数据执行的测试场景表明,所提出的算法能够提供更快的训练,并提高了针对入侵者的鲁棒性,比如众所周知的联邦平均算法。

Adaptive speed control of ROVs with experimental results from an aquaculture net pen inspection operation 机器人自适应速度控制与水产养殖网栏检查实验结果

Remotely operated vehicles (ROVs) are often used for inspection in aquaculture net pens which serves the important purpose of localizing holes in the net and reporting potential irregularities and damages. Manual control of the vehicle inside a net pen, while simultaneously inspecting the net structure, is difficult and puts a lot of stress on the vehicle operators. Adaptation of new solutions that enables autonomous traversal of net pens where the vehicle maintains a fixed distance, heading, and velocity relative to the net is considered essential. One of the main challenges of such autonomous solutions is a robust and tight control of the vehicle’s velocities. To target this challenge, this paper presents adaptive speed controllers for the surge and sway speeds of a remotely operated vehicle with unknown parameters and under the influence of unknown external disturbances. The stability properties of the controllers are proven through Lyapunov theory, and both simulations and field experiments demonstrate their ability to track the desired speeds through the use of a net following scheme.
远程操作车辆(rov)经常用于水产养殖网圈的检查,其重要目的是定位网洞并报告潜在的违规和损坏情况。人工控制网圈内的车辆,同时检查网的结构,是困难的,给车辆操作员带来很大的压力。适应新的解决方案,使车辆能够在相对于网保持固定距离、航向和速度的情况下自主穿越网圈,被认为是必不可少的。这种自动驾驶解决方案的主要挑战之一是对车辆速度的强大而严格的控制。针对这一挑战,本文针对未知参数和未知外部干扰影响下的遥控车辆的喘振和摇摆速度提出了自适应速度控制器。通过李雅普诺夫理论证明了控制器的稳定性,仿真和现场实验都证明了它们通过使用网络跟踪方案跟踪期望速度的能力。

While existing algorithms for open water navigation typically address path following and COLREGS compliant collision-avoidance, the unique challenges of inland waterways require a more tailored approach. We propose a two-level control strategy that employs Model Predictive Control (MPC) and Scenario-Based Model Predictive Control (SB-MPC) for path following and collision-avoidance. The algorithm proposes integrated strategies for handling riparian land, static obstacles, and dynamic obstacles. The method is tested in simulation

Cooperative control of multi-UAV systems has attracted substantial research attention due to its significance in various application sectors such as emergency response, search and rescue missions, and critical infrastructure inspection. This paper proposes a distributed control algorithm to generate collision-free trajectories that drive the multi-UAV system to completely inspect a set of 3D points on the surface of an object of interest. The objective of the UAVs is to cooperatively inspect the object of interest in the minimum amount of time. Extensive numerical simulations for a team of quadrotor UAVs inspecting a real 3D structure illustrate the validity and effectiveness of the proposed approach.
多无人机系统协同控制在应急响应、搜救任务、关键基础设施巡检等多个应用领域具有重要意义,引起了广泛的研究关注。本文提出了一种分布式控制算法,用于生成无碰撞轨迹,驱动多无人机系统对感兴趣物体表面上的一组三维点进行完全检测。无人机的目标是在最短的时间内协同检查感兴趣的目标。对一组四旋翼无人机检测真实三维结构的大量数值模拟表明了该方法的有效性和有效性。
