Dual-Flatness-Based-Control Strategy of Modular Multilevel Matrix Converter
IEEE International Conference on Power and Renewable Energy, 2021The Modular Multilevel Matrix Converter can realize the three-phase AC-AC transformation. Its outstanding advantages are easy to modularize, high reliability and low harmonic content, which can be used in high-voltage and large-capacity driven system ...

Flatness based Control of a Gantry Crane
IFAC Proceedings Volumes, 2013Abstract This contribution deals with flatness based control of a laboratory model of a gantry crane. The mechanical model has 3DOFs, where a trolley can be moved on a rail, the load is fixed at the end of a rope and can be lifted or lowered by coiling or uncoiling this rope on a cylinder.

Flatness-based control of a continuous furnace
2009 IEEE Control Applications, (CCA) & Intelligent Control, (ISIC), 2009Generally 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 ...

Nonlinear Flatness-Based Observer for Vehicle Dynamics Control
IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021This paper describes a novel nonlinear flatness-based state observer for vehicle dynamics control. The differential flatness property of a nonlinear vehicle model is used to derive a state observer for the lateral dynamics of a vehicle. Furthermore, a second state observer for the combined lateral and longitudinal movement is presented.

Flatness based control of traffic flow
2006 IEEE Intelligent Transportation Systems Conference, 2006This paper is concerned with the traffic flow control using the concept of flatness. The proposed approach exploits the bond-graphs formalism in the macroscopic modeling of the traffic flow. The main advantage is that it allows to strongly simplify the analysis techniques, offering a physical comprehension of the dynamical behavior of the studied ...

A flatness-based approach to internal model control
2006 American Control Conference, 2006The design principle of internal model control (IMC) focuses on developing a feedforward controller which also acts in the feedback loop to attenuate disturbances. This paper uses ideas developed in the theory of flat systems for the design of feedforward controllers and adapts them to IMC control.

We present a flatness-based averaging control system (FACS), for the purpose of controlling a class of nonlinear systems, namely differentially flat systems. Discrete-time control system design methods are first presented. The methods pertain to FACS and classical feedback linearization and linear control. The methods are then applied to the control of

DESIGN OF FUZZY FLATNESS-BASED CONTROLLER FOR A DC DRIVE
Control and Intelligent Systems, 2010Summary: A combined approach associating the flatness principle to the fuzzy logic control techniques is proposed and applied to a DC drive supplied by an AC-DC power converter. The basic of this control strategy consists in planning a reference trajectory using the flatness property of linear systems.

Flatness-based control in successive loops for dual-arm robotic manipulators
Conference on Control Technology and ApplicationsDual-arm robotic manipulators are used in industry and for assisting humans since they enable dexterous handling of objects and more agile and secure execution of pick-and-place, grasping and lifting, or assembling tasks.

Flatness-based online controller reconfiguration
2008 34th Annual Conference of IEEE Industrial Electronics, 2008It is a frequent wish for mechatronic systems to be able to adapt themselves to changing environmental conditions at runtime. Self-adapting behavior may require complex reconfigurations of controllers in the shape of mode management and control algorithms. These changes ought to be executed at runtime without shutting the system down. As this procedure
