Time-independent feedbacks for the null controllability of homogeneous quasilinear hyperbolic systems in one dimensional space

We consider the null controllability of homogeneous quasilinear hyperbolic systems with one side controls and with nonlinear boundary condition at the other side. We present time-independent feedbacks for the null-controllability for

System-level, Input-output and New Parameterizations of Stabilizing Controllers, and Their Numerical Computation

Maryam Kamgarpour, Luca Furieri, Na Li

It is known that the set of internally stabilizing controller

\mathcal{C}_{\text{stab}}

is non-convex, but it admits convex characterizations using certain closed-loop maps: a classical result is the {Youla parameterization}, and two recent notions are t ...

Negative Resistance in Cascode Transistors

Elison de Nazareth Matioli, Armin Jafari, Palliyage Srilak Nirmana Perera

Cascode topology which includes a high-voltage GaN and a low-voltage Si transistor is an attractive device concept, which uses the low ON-resistance of GaN while still being compatible with Si gate drivers. It demonstrates the highest threshold voltage amo ...

Free Carrier Mobility, Series Resistance, and Threshold Voltage Extraction in Junction FETs

Jean-Michel Sallese, Farzan Jazaeri, Matthias Bucher

In this brief, extraction methods are proposed for determining the essential parameters of double gate junction field-effect transistors (FETs). First, a novel method for determining free carrier effective mobility, similar to a recently proposed method fo ...

Open loop control theory algorithms for high-speed 3D MEMS optical switches

There is a world-wide push to create the next-generation all-optical transmission and switching technologies for exascale data centers. In this paper we focus on the switching fabrics. Many different types of 2D architectures are being explored including M ...

Response of noise-amplifier flows: From linear control to nonlinear jet breakup

Isha Shukla

Among hydrodynamically unstable flows, the amplifier-flows are characterized by their large amplification potential in presence of external noise. Since amplifiers do not have an intrinsic dynamics, a chosen forcing can be applied to eventually control the ...

Activity induced synchronization: Mutual flocking and chiral self-sorting

Synchronization, the temporal coordination of coupled oscillators, allows fireflies to flash in unison, neurons to fire collectively, and human crowds to fall in step on the London millenium bridge. Here, we interpret active (or self-propelled) chiral micr ...

Linear-parameter-varying model predictive control for multi-region traffic systems

Nikolaos Geroliminis, Anastasios Kouvelas, Mohammadreza Saeedmanesh

An alternative approach for real-time network-wide traffic control in cities that has recently gained a lot of interest is perimeter flow control. The basic concept of such an approach is to partition heterogeneous cities into a small number of homogeneous ...

Model-based real-time plasma electron density profile estimation and control on ASDEX Upgrade and TCV

Federico Alberto Alfredo Felici, Cristian Galperti

Real-time plasma electron density profile estimation and control are essential in the operation of future tokamaks. In particular, the robustness against diagnostics failure and disturbances is important for long pulse operation. A model-based approach to ...

No-Regret Learning in Unknown Games with Correlated Payoffs

Maryam Kamgarpour, Andreas Krause, Ilija Bogunovic

We consider the problem of learning to play a repeated multi-agent game with an unknown reward function. Single player online learning algorithms attain strong regret bounds when provided with full information feedback, which unfortunately is unavailable i ...
