Input-to-state stabilization of feasible model predictive controllers for linear systems

Colin Neil Jones, Melanie Nicole Zeilinger

Research on sub-optimal Model Predictive Control (MPC) has led to a variety of optimization methods based on explicit or online approaches, or combinations thereof. Its foremost aim is to guarantee essential controller properties, i.e. recursive feasibilit ...

A fully integrated Hall sensor microsystem with current-mode output

Maher Kayal, Marc Pastre, Andrea Ajbl

This paper presents a fully integrated Hall sensor microsystem with a current-mode output. The system operates in open-loop and includes a Hall sensor with internal biasing, a fully differential front-end, a preamplifier chain and a voltage-to-current conv ...

Extracting energy from a flow: An asymptotic approach using vortex-induced vibrations and feedback control

François Gallaire, Philippe Meliga

This paper considers vortex-induced vibrations of a cylinder in water streams for renewable energy production. We use an analytical model recently obtained by the authors from the asymptotic analysis of a coupled flow-cylinder system, and assess the abilit ...

Fast polarizers installation for ECRH and ECE in TCV

Timothy Goodman, Federico Alberto Alfredo Felici, Laurie Porte

We report on the installation of fast polarizers for ECRH injection and ECE diagnostics, in the TCV tokamak. The main goal is to change the polarization during a plasma shot and react to changing conditions such as: plasma current and position, ECRH inject ...

A robust explicit nonlinear mpc controller with input-to- state stability guarantees

Colin Neil Jones

This article presents an algorithm for robust nonlinear explicit model predictive control. A low complexity receding horizon control law is obtained by approximating the optimal control law using multiscale basis function approximation. Feasibility and inp ...

A Navigation-Grade MEMS Accelerometer based on a Versatile Front End

Maher Kayal, Marc Pastre

This paper presents a MEMS-based 5th-order Delta Sigma capacitive accelerometer. The Delta Sigma loop is implemented in mixed signal, the global 5th-order filter having a 2nd-order analog and a 3rd-order digital part. The system can be used with a wide ran ...

Trot Gait Locomotion of A Cat Sized Quadruped Robot

Auke Ijspeert, Alexander Spröwitz, Mostafa Ajallooeian, Alexandre Tuleu

We are proposing and testing two model-free approaches for locomotion control of a light-weight, compliant, quadruped robot: open loop central pattern generators (CPG), and open and closed- loop dynamical movement primitives (DMP). We are presenting two di ...

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 ...

Closed-loop identication of MIMO systems: a new look at identifiability and experiment design

Ljubisa Miskovic

This paper addresses a question that has been posed to us:“Is it necessary to excite all reference signals for the identification of a multivariable system operating in closed loop with a linear time-invariant controller?” In this paper we follow a careful ...
