Modern factories collect and process a large volume of different types of industrial process data. These data are used to develop metrics and Key Performance Indicators to monitor and improve productivity and the efficiency of a factory. Improving the efficiency of an industrial process, however, This work develops an ontology-based framework that semantically describes an industrial process, and in particular it describes the elements of physical connectivity, industrial behaviour, and KPIs. Using a notion of sub-process hierarchy, a Decision Support System explores and suggests options for reconfiguring the elements of the industrial process, to improve efficiency. A proof-of-concept use-case from the KIOS Water System Testbed is presented. The pumping station (connectivity, behaviour and energy efficiency KPIs) of the Testbed is semantically modelled, whereas the DSS suggests reconfiguration options for improving its overall energy efficiency.

The linear matrix inequality approach is proposed to state control design of discrete-time linear positive systems, guaranteeing the closed-loop system positiveness, enabling attenuation of the impact of disturbances on the system and, if it is necessary, also giving possibility to mount limiting quadratic constraints on state variables into design conditions. Constructing the set of linear matrix inequalities warranting the strictly positive structure and the Lyapunov inequality forcing quadratic stability of the controlled system, the design conditions outlined and proven are the main results of the paper. The diagonal stabilizability had to be included into the set of linear matrix inequalities to construct the closed-loop schemes with a positive control law gain. The proposed approach is numerically illustrated.

This paper proposes a low-cost solution for localizing a remotely operated vehicle (ROV) inside a fish net pen. The solution consists of a kinematic Kalman Filter capable of estimating the absolute ROV position and orientation in a fish net pen using primarily the onboard compass, laser-camera triangulation, and a model of the cylindrical net pen. The solution is demonstrated in a real fish net pen, under realistic operating conditions, and the performance is comparable to that of specialized positioning sensor systems such as ultra short baseline systems and Doppler velocity loggers.

The new era of Industry 4.0 and its key-enabling Internet of Things technologies promises fundamental advances during data collection, processing and analysis from a variety of agents and sensors, for the collective benefit of society. In this regard, connected and autonomous vehicles equipped with integrated perception sensors and communication abilities formulate a cluster or swarm of intelligent nodes capable to transform the transportation sector into a new smart mobility system. However, its feasible operation may be potentially threatened by hijackers whose goal is to cause malfunctioning to critical vehicular sensors, harnessing the perception system of vehicle. Therefore, in this paper we discuss the impact of cyberattacks such as GPS spoofing on autonomous vehicles, and design efficient detection and mitigation centralized schemes which provide location awareness and security monitoring over the whole cluster of vehicles. More specifically, we exploit the cooperation among the interacting vehicles, and develop robust sparse coding solutions based on graph signal processing and Alternating Direction Method of Multipliers. Cooperative based approach is further benefited by a in-vehicle module which provides spoofing detection alerts at the level of individual vehicle. Experimental analysis using the renowned CARLA simulator indicates highly efficient mitigation performance for different rates of compromised vehicles, as well as spoofing detection metrics greater than 94%.

To overcome input saturation and loss of thrust effectiveness problems for multiple fixed-wing unmanned aerial vehicles (UAVs), a fault-tolerant cooperative control (FTCC) based on adaptive backstepping sliding mode control (BSMC) method is developed. An auxiliary dynamic system is constructed to solve the input saturation problem. Furthermore, adaptive laws are proposed to estimate the thrust effectiveness and lumped unknown term. Stability of the system and finite-time convergence of the error signals are proved by Lyapunov analysis. Finally, the effectiveness of the proposed control scheme is verified by the simulations.

This work considers the problem of passively monitoring multiple moving targets with a single unmanned aerial vehicle (UAV) agent equipped with a direction-finding radar. This is in general a challenging problem due to the unobservability of the target states, and the highly non-linear measurement process. In addition to these challenges, in this work we also consider: a) environments with multiple obstacles where the targets need to be tracked as they manoeuvre through the obstacles, and b) multiple false-alarm measurements caused by the cluttered environment. To address these challenges we first design a model predictive guidance controller which is used to plan hypothetical target trajectories over a rolling finite planning horizon. We then formulate a joint estimation and control problem where the trajectory of the UAV agent is optimized to achieve optimal multi-target monitoring.

Controlling platoons of heterogeneous vehicles is a relevant field of research. In terms of platoon architecture, many approaches to harness inter-vehicle communication to develop cooperative adaptive cruise control (CACC) systems have been investigated. For instance, optimal control has proven to yield high performance results. Yet, heterogeneity in vehicle dynamics over a platoon poses many challenges. For real world application, one major issue is the uncertainty of model parameters. Furthermore, differences in lagged response to a control input degrade performance criteria such as tracking and cohesion of a vehicle string. Adjusting the spacing with both the preceding and the succeeding vehicles using bidirectional communication can potentially improve the platoon cohesiveness and is crucial when considering the synchronized merging scenario. In this paper, an adaptive optimal controller is presented which relies on bidirectional platoon communication and deals with parameter uncertainties. Along with the adaptive optimal controller synthesis and string stability analysis, effectiveness of the controller is verified in a simulation example.

The perception of the environment is essential in mobile robotics applications as it enables the proper planning and execution of efficient navigation strategies. Optical sensors offer many advantages, ranging from precision to understandability, but they can be significantly impacted by lighting conditions and the composition of the surroundings. In contrast, millimeter wave (mmWave) radar sensors are not influenced by such adverse condition and are capable of detecting partially or fully obstructed obstacles, resulting in more informative point clouds. However, such point clouds are often sparse and noisy. This work presents Point2Depth, a cross-modal contrastive learning approach based on Conditional Generative Adversarial Networks (cGANs) to transform sparse point clouds from mmWave sensors into depth images, preserving the distance information while producing a more comprehensible representation. An extensive data collection phase was conducted to create a rich multimodal dataset with each information associated with a timestamp and a pose. The experimental results demonstrate that the approach is able to produce accurate depth images, even in challenging environmental conditions.

In this paper, we propose an algorithm that can measure obstacle distances in real time independent of brightness. The proposed method acquires camera information from a robot equipped with a cross-line laser and a monocular camera, binarizes only the cross-line laser light data using YUV values as threshold values, and calculates the ratio of color and luminance, thereby improving the method to measure the linear distance to obstacles in real time even in bright environments. Experimental results confirm that the proposed method can accurately detect the distance to obstacles. It was also able to accurately calculate the distance to obstacles even when the measurement environment was bright (717 Lux).

Data reconciliation is an essential tool in data processing in various industries. It helps to improve accuracy of decision-making algorithms by reducing the influence of random errors in measurements. In this paper, we consider large-scale data reconciliation problems in which multiple areas communicate over a network to obtain an optimal solution of the centralized problem. Our proposed approach accounts for the boundaries between different areas avoiding a mismatch and sub-optimality as well as reduces computational and communication complexities. The proposed distributed data reconciliation method is compared to a centralized reference in different scenarios.
