Wang, X. (author), Baldi, S. (author), Feng, Xuewei (author), Wu, Changwei (author), Xie, Hongwei (author), De Schutter, B.H.K. (author)

The vector field method was originally proposed to guide a single fixed-wing Unmanned Aerial Vehicle (UAV) towards a desired path. In this work, a non-uniform vector field method is proposed that changes in both magnitude and direction, for the purpose of achieving formations of UAVs. As compared to related work in the literature, the...

Hardware in the loop experiments on the interaction between a diesel-mechanical propulsion system and a ventilating propeller

Huijgens, L.J.G. (author), Vrijdag, A. (author), Hopman, J.J. (author)

The interaction between ship propulsion machinery, propellers and the highly dynamic environment which is the sea is a complex yet highly relevant subject. During a storm, for example, waves and ship motions may cause the propeller to draw air, or ventilate, resulting in rapid changes in propeller thrust and load torque. These fluctuations...

Supplementary control based on current source coupling for improving dynamic characteristics of active distribution network

Hou, Jue (author), Liu, Zhou (author), Wang, Shaorong (author), Chen, Zhe (author), Xie, Wei (author), Fang, Cheng (author), Wei, Xinchi (author), Popov, M. (author)

Supplementary control (SC) technology is widely leveraged by power supply companies in active distribution networks (ADNs) to improve their stability and dynamic characteristics. Yet, the existed SCs are generally implemented from inside the converter controllers of distributed generators (DGs) or active loads, so there is a need to redesign...

Wind load simulations and inertia scaling using an industrial robot arm

Klifman, Boyan (author)

Existing wind load simulators such as wind tunnels and fans have multiple disadvantages, especially when used in a scaled-down environment. This paper proposes to simulate wind loads by using an admittance-controlled industrial robot arm rigidly attached to a research object. Admittance control should make it possible to simulate wind loads and...

Dynamic behaviour of a propulsion plant and its controller: with Hardware In the Loop

Roberti, Ronald (author)

The shipping industry is forced to reduce its emissions and underwater radiated noise in order to decrease the impact on the environment and limit global warming. Moreover, a low acoustic signature can be lifesaving for a navy ship, especially during submarine on mine threats. To be able to operate as flexible as possible under these threats, a...

Hardware-in-loop Emulation of a Solar Array Fed Water Pumping System

Liu, Yujie (author)

Solar array fed water pumping system is a good approach for water management and agriculture purpose. PV panels highly depend on unpredictable environmental conditions, as a result, the development of a PV system is with more technical challenges. System-level simulation on a desktop computer has limitations, such as uncertain accuracy of the...

Event-triggered control for automotive systems: Theoretical analysis and experimental research

Lanka, Indeevar Shyam (author)

Vehicles are becoming increasingly complex and the resource-demanding due to the developments aimed at driving autonomy. Viewing an automobile as a cyber-physical system (CPS), this work applies the advances of controls applied to CPS for improving resource-consumption. One such idea is that of event-based control. Theoretical developments in...

Hardware in the Loop Emulation of Ship Propulsion Systems at Model Scale

Huijgens, L.J.G. (author)

Requirements on ships are rapidly increasing. In particular, safety and environmental impact are under increasing scrutiny. At the same time, cost and profitability remain as important as they have ever been. These increasingly stringent constraints are beginning to pose problems during the design process. For example, the energy efficiency...

Hardware in the loop experiments with ship propulsion systems in the towing tank: Scale effects, corrections and demonstration

Huijgens, L.J.G. (author), Vrijdag, A. (author), Hopman, J.J. (author)

Standards for environmental impact, safety and operational performance of ships are becoming increasingly strict. In order to meet these standards, the performance of new ship designs must be predicted with an increasing level of detail and confidence. As present prediction methods lack realistic, dynamic behaviour of the ship's propulsion plant...

Hardware-in-the-Loop Simulation of Controlled and Uncontrolled EV Charging in a Distribution Grid

De Herdt, Lode (author)

The charging of a rapidly increasing number of EVs places significant strain on electrical distribution grids. Controlled (’smart’) charging of EVs offers a solution to this problem by shifting the charging of vehicles to the most optimal moments in time. Smart charging is not a completely new research topic; it has a high Technology Readiness...
