Having a method for analyzing and designing regulators of controls that contain many current loops such as active filters is not a trivial task. There can be many parameters of regulators and filters that must be carefully selected in order to fulfill certain desired requirements. For instance, these can be stability, dynamic response, robustness u...
Conference Paper
In the EU-funded project OSMOSE, RTE and Ingeteam installed a 1 MVA demonstrator to show the technical and economical viability of building a grid-forming function upon a commercially available hybrid energy storage system. In this paper we share the experimental results obtained in a power hardware in the loop test bench during the Factory Accepta...
Conference Paper
The European research project MIGRATE, and especially its Work Package 3 (WP3) demonstrated that grid-forming controls for some converters is a necessary condition to operate a system without synchronous machines with a sufficient level of reliability [1]. Despite the limited overcurrent capability of the converters, several control concepts showed...
Article
In a Medium Voltage Direct Current (MVDC) multidrive system several power electronics converters share a common MVDC bus. The contribution of this work relies on the systematic modelling approach of MVDC multidrive systems for the analysis of the MVDC bus power quality. Particularly the interaction between the harmonics injected by the converters a...

Electric propulsion and integrated hybrid power systems can improve the energy efficiency and fuel consumption of different kinds of vessels. If the vessel power system is based on DC grid distribution, some benefits such as higher generator efficiency and lower volume and cost can be achieved. However, some challenges remain in terms of protection...
Article
Evolution of technology is significantly increasing the presence of hybrid-electric power systems in offshore (support/operation) vessels. They require high dynamic response including dynamic positioning and high levels of reliability and safety. This paper presents a methodology for the optimal design of hybrid-electric power systems for all-elect...
Article
The benefits of using Power Electronics Based DC Distribution Systems in electrically propelled vessels are well known. However, some aspects must be deeply analyzed to guarantee a safe, robust and stable system by design. This paper presents a multivariable DC Distribution System mathematical model, where all the transmission lines and filters imp...
Conference Paper
This paper presents an active damping control strategy especially designed to mitigate the effects of the resonances of low damped power electronic based DC distribution systems. In those systems, some controlled converters are connected to a common DC bus usually exhibiting negative impedance due to its operation as constant power loads. The activ...
Conference Paper
The benefits of using Power Electronics Based DC Distribution Systems in diesel-electric vessels are well known. However, some aspects must be deeply analyzed to guarantee a safe, robust and stable system by design. A multivariable DC Distribution System mathematical model is presented and described in this work, where all the transmission lines an...

Resumen Los buques destinados a realizar operaciones especiales lejos de la costa requieren un control de velocidad y de posicionamiento de alta precisión y respuesta dinámica. Condiciones adversas de oleaje y/o meteorológicas provocan fuertes perturbaciones que el sistema de control debe rechazar para garantizar un posicionamiento preciso (sobre u...
Article
This work presents a real time testing approach of an Intelligent Multiobjective Nonlinear-Model Predictive Control Strategy (iMO-NMPC). The goal is the testing and analysis of the feasibility and reliability of some Soft Computing (SC) techniques running on a real time industrial controller. In this predictive control strategy, a Multiobjective Ge...

This paper presents an approach to merge three elements that are usually not thought to be combined in one application: evolutionary computing running on reasonably priced microcontrollers (μC) for real-time fast control systems. A Multi Objective Genetic Algorithm (MOGA) is implemented on a 180MHz μC.A fourth element, a Neural Network (NN) for sup...
Conference Paper
The prediction of the driving cycle (vehicle speed profile versus time) and the road grade cycle (road grade profile versus time) can improve a variety of vehicle functions, especially the energy management of HEVs and PHEVs. The variability of the driving conditions (environment) together with the nonlinear and variable driver behaviour (driving s...
Conference Paper
A Networked Range Extended Electric Vehicle (NCV2015) has been developed as a mobile platform for researching in technologies, powertrain system components and control algorithms for the future generation of low environmental impact electrified vehicles. An overview of the NCV2015 vehicle, including its control & I2V (Infrastructure to Vehicle) com...
Conference Paper
By testing advanced control techniques based on Soft Computing into industrial platforms is possible to analyse the feasibility and reliability of these implementations for being subsequently used in real industrial processes. In many cases, this fact is not taken into account for several reasons concerning with the complexity of performing hardwar...

The electrification of road transport is opening new opportunities and challenges to the automotive industry. The design and development of high performance, low weight–size and cost, reliable, safe and high energy efficient electric/hybrid powertrains are crucial for the successful introduction of the new generation of electric and hybrid vehicles...
Article
The benefits of using the Nonlinear Model Predictive Control (NMPC) for the response optimization of highly complex controlled plants are well known. Nevertheless the complexity and associated high computational cost make its implementation and reliability the focus of the discussion. This paper proposes an Intelligent and Multi-Objective NMPC (iMO...

A real-time control system for the powertrain management of a Range Extended Electric Vehicle (RE-EV) is presented in this paper. Aspects such us the powertrain supervisory control and the energy/power management are taken into account in the overall powertrain control strategy with the objective of increase the vehicle range when reducing at the s...
Conference Paper
Hybrid ship is a vehicle which can use two or more methods of energy storage. In normal operation the fuel energy is consumed for propulsion, but in some circumstances, as braking or wind thrusted, energy can be generated and stored. This paper shows the modeling and energy generation results obtained during sailing with a hybrid ship in the genera...

Nowadays car development time from concept approval to Job 1 is between 2 and 5 years (with an average of 3 years), but in the coming years is necessary to reduce it in order to achieve the optimal 12-month car. On the other hand the penetration rate of alternative powertrains (electric, hybrid) is growing quickly, increasing the complexity of the...
