Funnel Control Via Funnel Precompensator for Minimum Phase Systems With Relative Degree Two

IEEE Transactions on Automatic Control, 2018
We consider tracking control for linear minimum phase single-input, single-output systems with relative degree two. For a class of sufficiently smooth reference signals, we introduce a dynamic controller which achieves that the tracking error evolves within a prespecified performance funnel.

Controlling Light Emission with Photonic Funnels

Conference on Lasers and Electro-Optics, 2022
We analyze the interaction between a nanoscale emitter and a photonic funnel with a metamaterial core and demonstrate that funnel structures can significantly improve out-coupling efficiency of light as compared with their planar plasmonic counterparts.

Funnel Control for the Boundary Controlled Heat Equation

SIAM Journal on Control and Optimization, 2015
Summary: We consider an output regulation problem for a single input single output system with dynamics described by the heat equation on some bounded domain \(\Omega\subset\mathbb R^d\) with sufficiently smooth boundary. The input is formed by Neumann boundary control, and the output is the surface integral of the state at the boundary.

Funnel control for electrical circuits

PAMM, 2014
AbstractWe study the zero dynamics and funnel control for linear passive electrical circuits. We show that asymptotic stability of the zero dynamics can be characterized by criteria on the circuit topology. Thereafter we consider the output regulation problem for electrical circuits by funnel control.

Funnel-Control in robotics: An introduction

2008 16th Mediterranean Conference on Control and Automation, 2008
An adaptive (time-varying) MIMO/SISO control strategy - funnel-control - for position control of nonlinear, coupled (rigid) robotic systems is presented and its applicability in robotics introductory shown. The concept is based on the high-gain controllability of minimum-phase systems with relative degree one and known high-frequency gain. The approach

Fault tolerant funnel control

PAMM, 2018
AbstractA new approach to adaptive fault tolerant tracking control for uncertain linear systems is presented. Based on recent results in funnel control and the time‐varying Byrnes‐Isidori form, we introduce a low‐complexity model‐free controller which achieves prescribed performance of the tracking error for any given sufficiently smooth reference ...

Funnel control in mechatronics: An overview

IEEE Conference on Decision and Control and European Control Conference, 2011
This overview presents a simple high-gain adaptive controller — the funnel controller — and its possible applications in mechatronics. The funnel controller neither identifies nor estimates the system under control and is applicable for (nonlinear) systems being minimum-phase (or having stable zero-dynamics in the nonlinear case), having relative ...
