Robust H-infinity Controller Design Using Frequency-Domain Data via Convex Optimization

Alireza Karimi, Achille Nicoletti, Yuanming Zhu

A new robust controller design method that satisfies the H-infinity criterion is developed for linear time-invariant single-input single-output (SISO) systems. A data-driven approach is implemented in order to avoid the unmodeled dynamics associated with p ...

Multiple roles of lymphatic vessels in peripheral lymph node development

Borja Prat Luri, Esther Bovay, Ann-Helen Willrodt

The mammalian lymphatic system consists of strategically located lymph nodes (LNs) embedded into a lymphatic vascular network. Mechanisms underlying development of this highly organized system are not fully understood. Using highresolution imaging, we show ...

Stochastic impulse control with regime-switching dynamics

Yaroslav Melnyk

Optimal product management problems with multiple product generations in continuous time lead to the consideration of dynamic optimal control problems that feature both intervention costs and partially controlled regime shifts. We therefore investigate and ...

Fixed-structure Control of LTI Systems with Polytopic-type Uncertainty

Mahdieh Sadat Sad Abadi

This thesis focuses on the development of robust control solutions for linear time-invariant interconnected systems affected by polytopic-type uncertainty. The main issues involved in the control of such systems, e.g. sensor and actuator placement, control ...

Non-Parametric Estimation of Surface Temperature of Li-ion Cells using Thermal Impulse Response

Mario Paolone, Dimitri Torregrossa, Ying Xiao

This paper focuses on the prediction of temperature profiles on the surface of lithium-ion cells using a non-parametric method. In particular, this paper proposes the adoption of the impulse response technique to compute and interpret cell surface temperat ...

Interaction between counterpropagating Rossby waves and capillary waves in planar shear flows

François Gallaire, Luca Biancofiore

A counterintuitive destabilizing effect of the surface tension in planar wakes has been observed by Tammisola et al. ["Effect of surface tension on global modes of confined wake flows," Phys. Fluids 23, 014108 (2011)] and Biancofiore et al. ["Direct numeri ...

On the MIMO Capacity for Distributed System under Composite Rayleigh/Rician Fading and Shadowing

José Luis Padilla de la Torre

Wireless channels are commonly affected by short-term fading and long-term fading (shadowing). The shadowing effects must be taken into account also when mobility is present in the wireless scenario. Using a composite fading model, the total channel capaci ...

Fixed-order Controller Design for State Space Polytopic Systems by Convex Optimization

Alireza Karimi

In this paper, a new method for fixed-order controller design of systems with polytopic uncertainty in their state space representation is proposed. The approach uses the strictly positive realness (SPRness) of some transfer functions, as a tool to decoupl ...

Phase Analysis of the Stretching Cycles of the Head of Unsteady Gravity Currents Developing over Smooth and Rough Beds

Mário Jorge Rodrigues Pereira Da Franca, Helena Isabel Dos Santos Nogueira, Claudia Adduce

Gravity currents are buoyancy driven flows occurring spontaneously in nature or resulting from human intervention. Examples of gravity currents in the water are oceanic fronts, resulting from differences in temperature and salinity, and turbidity currents ...

Implementation Aspects of Model Predictive Control for Embedded Systems

Timm Faulwasser

In this paper we discuss implementation related aspects of model predictive control schemes on embedded platforms. Exemparily we focus on fast gradient methods and present results from an implementation on an embedded lowcost ARM processor. We show that in ...
