Robust stability properties of soft constrained MPC

Colin Neil Jones, Melanie Nicole Zeilinger

In Model Predictive Control, the enforcement of hard state constraints can be overly conservative or even infeasible, especially in the presence of disturbances. This work presents a soft constrained MPC approach that provides closed- loop stability even f ...

Fast Explicit Nonlinear Model Predictive Control Via Multiresolution Function Approximation with Guaranteed Stability Nonlinear Control Systems

Colin Neil Jones, John Lygeros

In this paper an algorithm for nonlinear explicit model predictive control is introduced based on multiresolution function approximation that returns a low complexity approximate receding horizon control law built on a hierarchy of second order interpolets ...

A new tandem mass spectrometer for photofragment spectroscopy of cold, gas-phase molecular ions

Thomas Rizzo, Ulrich Lorenz, Annette Svendsen

We present here the design of a new tandem mass spectrometer that combines an electrospray ion source with a cryogenically cooled ion trap for spectroscopic studies of cold, gas-phase ions. The ability to generate large ions in the gas phase without fragme ...

Reusable Localized Surface Plasmon Sensors Based on Ultrastable Nanostructures

Noelia Laura Bocchio

Nanoparticle arrays created by nanosphere lithography are widely used in sensing applications since their localized surface plasmon resonances are extremely sensitive to changes in the local dielectric environment. A major drawback for any biologically ori ...

Integrated Design and Optimization of Gas Bearing Supported Rotors

Daniel Favrat, Jürg Alexander Schiffmann

The design of direct driven turbomachinery is an interdisciplinary task. Standard design procedures propose to split such systems into subcomponents and to design each one individually. This common procedure, however, tends to neglect the interactions betw ...

Global Stabilization of an Inverted Pendulum – Control Strategy and Experimental Verification

Dominique Bonvin

The problem of swinging up an inverted pendulum on a cart and controlling it around the upright position has traditionally been treated as two separate problems. This paper proposes a control strategy that is globally asymptotically stable under actuator s ...

Experimental vertical stability studies for ITER performance and design guidance

Jonathan Bryan Lister

Operating experimental devices have provided key inputs to the design process for ITER axisymmetric control. In particular, experiments have quantified controllability and robustness requirements in the presence of realistic noise and disturbance environme ...

Data-driven controller validation

Dominique Bonvin, Alireza Karimi, Klaske van Heusden

This paper proposes a data-driven test for closed-loop stability. The test is based on a non-conservative stability condition that can be veriﬁed without having to actually implement the controller. It uses a set of measurements from the plant but does not ...

Existence And Stability Of High Frequency Standing Waves For A Nonlinear Schrodinger Equation

François Samer Genoud

This article is concerned with the existence and orbital stability of standing waves for a nonlinear Schrodinger equation (NLS) with a nonautonomous nonlinearity. It continues and concludes the series of papers [6, 7, 8]. In [6], the authors make use of a ...

Study of twinned dendrite growth stability

Michel Rappaz, Mario Alberto Salgado Ordorica, Jonas Valloton

Under certain thermal conditions (G approximate to 1 x 10(4) K/m, v(s) approximate to 1 x 10(-3) m/s), < 1 1 0 > twinned dendrites appear in aluminum alloys and can overgrow regular columnar dendrites, provided that some convection is also present in the m ...
