Modeling of High-Frequency Electromagnetic Effects on an Ironless Inductive Position Sensor

Yves Perriard, Alessandro Danisi, Alessandro Masi

The ironless inductive position sensor (I2PS) is a five-coil air-cored structure that senses the variation of flux linkage between supply and sense coils and relates it to the linear position of a moving coil. In air-cored structures, the skin and proximit ...

Plug-and-Play Decentralized Model Predictive Control for Linear Systems

Giancarlo Ferrari Trecate, Marcello Farina

In this paper we consider a linear system structured into physically coupled subsystems and propose a decentralized control scheme capable to guarantee asymptotic stability and satisfaction of constraints on system inputs and states. The design procedure i ...

Converter placement in the interconnection of railway power grid and public power grid based on cost-reliability approach

Mokhtar Bozorg, Daniel Lopez

The railway load in Switzerland is expected to increase in the next years. Increasing the capacity of the interconnection between the railway power system and the public grid is a reasonable solution to deal with this problem. This paper proposes a way to ...

Decoupled dq-Current Control of Grid-Tied Voltage Source Converters Using Nonparametric Models

Alfred Rufer, Alireza Karimi, Behrooz Bahrani

This paper presents a vector control strategy for regulating the current of grid-tied voltage source converters (VSCs) in a rotating reference frame. The proposed approach is based on shaping the open-loop and closed-loop transfer matrices of the system. S ...

Contribution to the Active Generator Principle

Antoine Béguin

This work is part of the innovative "Active Generator" (AG) project. AG is a concept that suggests a new arrangement of the turbine-generator line of a high power utility (a few hundred of MW) in order to de-synchronize the rotation speed of the turbine-ge ...
