Non-Iterative Data-Driven Model Reference Control

In model reference control, the objective is to design a controller such that the closed-loop system resembles a reference model. In the standard model-based solution, a plant model replaces the unknown plant in the design phase. The norm of the error betw ...

Accounting for congestion and spillbacks in fixed-time traffic signal optimization: an analytical queueing model approach

Michel Bierlaire, Carolina Osorio Pizano

We present and analyze a new aggregate model of urban traffic. The objective is to analytically capture the correlation between the different components of the network while maintaining a tractable model that can be used in an optimization framework. Exist ...

How can human motion prediction increase transparency?

Jamie Paik

A major issue in the field of human-robot interaction for assistance to manipulation is transparency. This basic feature qualifies the capacity for a robot to follow human movements without any human-perceptible resistive forces. In this paper we address t ...

Proposal to Extend SystemC-AMS with a Bond Graph Based Model of Computation

Yusuf Leblebici, Alain Vachoux, Torsten Mähne

There is a need to improve the modelling capabilities of SystemC-AMS concerning conservative continuous time systems involving the interaction of several physical domains and the interaction with digital control components. Bond graphs unify the descriptio ...

Proposal for a Bond Graph Based Model of Computation in SystemC-AMS

Alain Vachoux, Torsten Mähne

SystemC-AMS currently offers modelling formalisms with specialised solvers mainly focussing on the electrical domain. There is a need to improve its modelling capabilities concerning conservative continuous time systems involving the interaction of several ...

New error amplifier topology for Low Dropout Voltage regulators using compound OTA-OPAMP

Maher Kayal

Typical Low Dropout Voltage regulators (LDO), uses an error amplifier in a linear closed loop. The main advantage of such linear regulators is the low standby current due to the absence of switching. In addition, a fully integrated linear regulator with no ...

A mathematical approach in the design of arterial bypass using unsteady Stokes equations

Alfio Quarteroni, Gianluigi Rozza

In this paper we present an approach for the study of aorto-coronaric bypass anastomoses configurations using unsteady Stokes equations. The theory of optimal control based on adjoint formulation is applied in order to optimize the shape of the zone of the ...

Shape design in aorto-coronaric bypass anastomoses using perturbation theory

Alfio Quarteroni, Gianluigi Rozza

We present a new approach in the study of aorto-coronaric bypass anastomoses configurations based on small perturbation theory. The theory of optimal control based on adjoint formulation is applied in order to optimize the shape of the zone of the incoming ...

Digital control system for the TCV Tokamak

Basil Duval, Jean-Marc Moret

This paper presents the hardware and software approach to replacing the current analogue linear feedback system on the TCV Tokamak with a DSP based system to allow for non-linear control. After preliminary combination, over 120 control signals are reduced ...

On cooperation via noisy feedback

Michael Christoph Gastpar

An upper bound is established on the usefulness of noisy feedback for the two-user multiple-access channel (MAC). The bound generalizes a dependence-balance argument developed by Hekstra and Willems for the common-output two-way channel and the MAC with no ...
