The Matrix Converter concept was first published in the 1970‟s, but the advantages of the topology in terms of weight and volume have yet to find widespread applications in industry. In this presentation the advantages and disadvantages of the topology will be explored and a full range of direct AC/AC power converter topologies will be introduced including two-stage Matrix Converters and Multi-level Matrix Converters. Enabling techniques and strategies for Matrix Converter modulation, current commutation and circuit protection will be explained. The presenation will also consider the technology required for the successful design, construction and testing of Matrix Converters as well as considering the emerging applications for this power converter circuit. The presentation will draw on examples of hardware as well as the large pool of knowledge and experience from the team at the University of Nottingham, including a SiC JFET Matrix Converter demonstrating >20kW/Litre.
This presentation will introduce the More Electric Aircraft concept and investigate the potential benefits of the technology for manned, civilian aircraft. Typical aircraft electrical
power systems, electrical power generation arrangements and associated aircraft loads will be described as well as the exciting, future challenges for the aerospace industry. The importance
of power electronics as an enabling technology for this step change in aircraft design is considered and examples of typical system designs are discussed. Work undertaken at Nottingham on
Actuation for Helicopters and Power Converters for Fuel Cell applications as part of the Clean Sky JTI programme will be described and future challenges for academia and industry will be

Titulo: A port-Hamiltonian formulation of a 2D boundary controlled acoustic system. Resumen/Abstract: This talk deals with the port Hamiltonian formulation of a 2D boundary controlled acoustic system. The system under consideration consits of an acoustic wave traveling in a tube equipped with a network of microphones/loudspeakers. The purpose of this smart skin is to damp the acoustic wave and reduce its effect at the output of the tube.. The overall system (wave+actuators/sensors) is finally expressed as a port Hamiltonian control system and a stabilizing distributed control law is proposed.
Profesor Hector Ramírez U. de Franche-Comte / Laboratorio FEMTO-ST Besancon, Francia
Biografía: Hector Ramirez received the degrees in Electronic Engineering and Master in Engineering Science from the University of Concepcion, Chile in 2006 and 2009 respectively. In 2012 he received the Doctor degree in Engineering Sciences from the University of Concepcion, Chile and the Doctor degree in Automatic Control from the University Claude Bernard - Lyon 1, France. He held a postdoc position at the department of Automatique et Systèmes Micro-Mécatroniques at FEMTO-ST, in Besançon, France. He is currently associate professor at the University of Franche-Comté. His research concerns the modelling and control of complex physical systems using energy based approaches. More specifically, it focuses on the use of port-Hamiltonian system for the structural modelling and control of systems described by ordinary and partial differential equations arising from different physical domains. The main applications of his research activities are micro/nano-electromechanic and thermodynamic systems. He is member of the IFAC Technical Committee on Non-linear Control Systems (TC2.3) since September 2014.
