Plug-and-Play Decentralized Model Predictive Control

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 ...

Power and DC Link Voltage Control Considerations for Indirect AC/AC Modular Multilevel Converters

Alfred Rufer, Michail Vasiladiotis, Stephan Kenzelmann, Nicolas Cherix

A highly interesting application field of the Modular Multilevel Converter is the interconnection of the European three-phase 50 Hz industrial grid with the single-phase 16 2/3 Hz railway supply. Contrary to existing technologies, the utilization of a bulk ...

Robust gain-scheduled blending control of raw-mix quality in cement industries

Alireza Karimi, Michael Amrhein, Vinicius De Oliveira

This paper addresses the control of the blending process in cement industries. This process can be modeled by a nonlinear multivariable system with large parametric uncertainty. Using a specific transformation, a linear parameter varying (LPV) model with s ...

AC analysis of defect cross sections using non-radiative MPA quantum model

Alexandre Schmid, Yusuf Leblebici, Davide Garetto

A multiphonon-assisted model included in a Poisson-Schroedinger solver has been applied for the calculation of the capture/emission trapping rates of Si/SiO2 interface defects and their dependence with respect to the trap energy and depth in the oxide. The ...

Robust Controller Design by Convex Optimization based on Finite Frequency Samples of Spectral Models

Alireza Karimi, Roland Longchamp, Gorka Galdos Sanz de Galdeano

Some frequency-domain controller design problems are solved using a finite number of frequency samples. Consequently, the performance and stability conditions are not guaranteed for the frequencies between the frequency samples. In this paper, all possible ...

Robust fixed-order H infinity Controller Design for Spectral Models by Convex Optimization

Alireza Karimi, Roland Longchamp, Gorka Galdos Sanz de Galdeano

A new approach for robust fixed-order

H_\infty

controller design by convex optimization is proposed. Linear time-invariant single-input single-output systems represented by a finite set of complex values in the frequency domain are considered. It is show ...

Robust Pole Placement of Systems with Polytopic Uncertainty Via Convex Optimization

Alireza Karimi, Roland Longchamp, Hamid Khatibi

Convex parameterization of fixed-order robust stabilizing controllers for systems with polytopic uncertainty is represented as an LMI using KYP Lemma. This parameterization is a convex inner-approximation of the whole non-convex set of stabilizing controll ...

Non-Equilibrium State Capacitor-Voltage Stabilization in a Hybrid Asymmetric Nine-Level Inverter: Non-Linear Model-Predictive Control

Alfred Rufer, Martin Veenstra

In symmetric multilevel inverters, there is a tradeoff between the output quality and the reliability and efficiency of the converter. New asymmetric and hybrid solutions, using different voltages and devices in various parts of the inverter, promise signi ...

Traffic-responsive urban network control using multivariable regulators

The paper presents the philosophy, the aim, the development, the advantages, and the potential shortcomings of the TUC (Traffic-responsive Urban Control) strategy. Based on a store-and-forward modeling approach and using well-known methods of the Automatic ...

Vector Control of an Induction Machine in a Stator Flux Reference Frame.

Jean-Jacques Simond, Basile Kawkabani, Mai Tu Xuan, Alexander Schwery

This paper describes a stator flux oriented control strategy using state space controllers. The optimal determination of the different controllers parameters leads to an independent control of the stator flux and the torque. The effects of undesired offset ...
