Flatness-based Temperature Control of Metal Sheets.

IFAC Proceedings Volumes, 2010
Abstract In order to enhance the performance of a class of lab-scale annealing testbeds for the steel industries, this paper addresses the temperature tracking task of sheet metal specimen by invoking nonlinear model-based control theory. Based on an accurate mathematical model of the testbed, which uses Ohmic heating via a phase-controlled power ...

Flatness-Based Control of Flexible Motion Systems

ASME 2011 Dynamic Systems and Control Conference and Bath/ASME Symposium on Fluid Power and Motion Control, Volume 1, 2011
Flexibility is often an unavoidable limitation when large-workspace high-speed manipulation is required. This flexibility can be mitigated in some circumstances through feedback control methods. However, these methods only correct for vibration after it has been measured. Therefore, if low-vibration reference commands can be generated, then the utility

Flatness based control for chaotic boost converters

2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004
This paper is about a control concept that offers both: 1) fast and smooth equilibrium-to-equilibrium transfers and almost perfect tracking of desired reference trajectories for non-minimum phase systems despite sudden load changes, and 2) a simple method to reduce electromagnetic interference (EMI) at the source.

Flatness-Based Control of Drilling Vibrations

2015
In nonlinear systems theory, the flatness property refers to the ability for dynamical systems of being exactly linearized via endogenous feedback. A system satisfying the flatness property is called a differentially flat system. The main attribute of flat systems is that the state and input variables can be directly expressed without integrating any ...

Flatness-based control of MIMO linear systems

2009 6th International Multi-Conference on Systems, Signals and Devices, 2009
This paper, deals with a control method of linear multi-input multi-output (MIMO) system, developed in order to ensure the tracking of a reference trajectory. The flatness-based controller for studied system allows to solve path planning and path tracking problems.

Flatness-based control of a continuous furnace

2009 IEEE International Conference on Control Applications, 2009
Generally speaking transport processes are typically modeled as distributed parameter systems. Most existing approaches to the control of such systems demand a high computational effort or are based on an approximation of the model. In this contribution, by attaching the sensors to the moving goods, two new flatness-based tracking control strategies ...

Flatness-based Control of Torsional-Axial Coupled Drilling Vibrations

IFAC Proceedings Volumes, 2014
The main purpose of this contribution is the control of both torsional and axial vibrations occurring along a rotary oil well drilling system. The considered model consists of a system of wave equations with non-linear coupled boundary conditions. We propose a flatness-based control approach to tackle the trajectory tracking problem guaranteeing the ...

Flatness-Based Control of a Simplified Wastewater Treatment Plant

2006 IEEE International Conference on Control Applications, 2006
This paper presents a nonlinear control approach for a simplified activated sludge model that covers the reduction of biodegradable substrate in biological wastewater treatment. In the proposed control scheme, the volume flow of oxygen into the aeration tank and the volume flow of excess sludge out of the settler tank are utilized as manipulated ...

Diesel Boost Pressure Control using Flatness-Based Internal Model Control

SAE Technical Paper Series, 2006
<div class="htmlview paragraph">As a result of the increased complexity of today's power trains, the traditional ways of designing engine control systems essentially through ad hoc methods and experimental tuning will no longer provide the desired level of performance. Further, it is too time-consuming due to the calibration process.

Flatness-Based Active Vibration Control for Piezoelectric Actuators

IEEE/ASME Transactions on Mechatronics, 2013
The accuracy and resolution of metrological devices (coordinate measuring machines -CMM-, interferometers, etc.) are greatly affected by their robustness to external vibrations. This is especially important in the case of micrometric and nanometric microscopes, such as atomic force microscopes (AFM).
