    The UAV industry is developing rapidly and drones are increasingly used for monitoring industrial facilities. When designing such systems, operating companies have to find a system configuration of multiple drones that is near-optimal in terms of cost while achieving the required monitoring quality. Stochastic influences such as failures and maintenance have to be taken into account. Model-based systems engineering supplies tools and methods to solve such problems. This paper presents a method to model and evaluate such UAV systems with coloured Petri nets. It supports a modular view on typical setup elements and different types of UAVs and is based on UAV application standards. The model can be easily adapted to the most popular flight tasks and allows for estimating the monitoring frequency and determining the most appropriate grouping and configuration of UAVs, monitoring schemes, air time and maintenance periods. An important advantage is the ability to consider drone maintenance processes. Thus, the methodology will be useful in the conceptual design phase of UAVs, in monitoring planning, and in the selection of UAVs for specific monitoring tasks

    Geographically distributed real-time co-simulation of electric vehicle

    The present paper shows the capabilities of a distributed real-time co-simulation environment merging simulation models and testing facilities for developing and verifying electric vehicles. This environment has been developed in the framework of the XILforEV project and the presented case is focused on a ride control with a real suspension installed on a test bench in Spain, which uses real-time information from a complete vehicle model in Germany. Given the long distance between both sites, it has been necessary to develop a specific delay compensation algorithm. This algorithm is general enough to be used in other real-time co-simulation frameworks. In the present work, the system architecture including the communication compensation is described and successfully experimentally validated

    Validation of Integrated EV Chassis Controller Using a Geographically Distributed X-in-the-loop Network

    This paper presents the validation of an integrated chassis controller that unites three groups of actuators for the electric vehicle (EV) with independent in-wheel electric motors (IWMs) for each wheel. Controlled actuators are the IWMs, the active suspension, and the braking system. The models of test benches and the designed architecture of the X-in-the-loop network are presented. The proposed design approach allows testing the developed controller on a vehicle model in real-time and on hardware components

    Innovative e-Machine and Power Electronics Solutions for e-Axle and e-Corner Vehicle Powertrains

    <p>The Horizon Europe EM-TECH and HighScape projects address innovative solutions for automotive electric powertrains, to achieve higher energy efficiency, reduced volume and mass, as well as reduced cost. The two projects are distinct yet complementary and synergic, where the former focuses on electric machines (e-Machines), while the latter on wide bandgap (WBG) based power electronics (PE). This paper outlines the main innovations of EM-TECH and HighScape, targeting a wide range of vehicle applications, including passenger cars and commercial vehicles. Specifically, EM-TECH deals with: i) modular designs of on-board axial flux machines (AFMs) for reducing the implementation costs of scalable centralised powertrains for electric axle (e-Axle) solutions; ii) in-wheel motors (IWMs) integrated with electric gearing, for expanding the high efficiency region of electric corner (e-Corner) powertrains; and iii) the use of permanent magnets deriving from recycling processes to improve sustainability. In parallel, HighScape targets the physical and functional integration of the PE of WBG based traction inverters, onboard chargers, DC/DC converters, and electric drives for auxiliaries and actuators.</p&gt
