Flatness Based Control of an Injection Moulding Machine
2013This contribution deals with the modelling and control of an injection moulding process. In injection moulding especially the appearance of a work piece depends much on the exact compliance with certain trajectories of temperature or pressure in the mould.

Linear predictive control revisited: A flatness based approach
1999 European Control Conference (ECC), 1999A novel formulation of linear model-based predictive control is presented. Predicted flat output trajectories and stabilization around these trajectories constitute the main components of our predictive control approach. A simple dc motor and a cement mill model illustrate the principal features of the method.

Real-time flatness-based control of a DC motor
2007 14th IEEE International Conference on Electronics, Circuits and Systems, 2007In this paper, an approach of design and develop a real-time system around RISC microcontroller dedicated to the DC motor speed control is proposed. A polynomial RST controller based on the flatness property of linear systems is implemented with C/C++ embedded programming language.

Guidance and Control for Planetary Landing: Flatness-Based Approach
IEEE Transactions on Control Systems Technology, 2013The guidance, navigation, and control problems for autonomous planetary entry descent and landing pose a number of interesting challenges. In this paper, the guidance and control problems for the descent phase are considered, and an approach based on the flatness property of the descent equations is proposed.

Flatness-Based Control of Drilling Vibrations
2015In 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 a flexible beam in a gravitational field
Proceedings of the 2004 American Control Conference, 2004This paper considers a flatness-based boundary control of a hub-beam system with tip payload moving in a vertical plane in the presence of gravity. The homogeneous flexible beam is modelled using an Euler-Bernoulli hypothesis which assumes no shear deformation or rotatory inertia. As well, small transverse deformations are assumed.

Flatness-Based Feedback Control of an Automotive Solenoid Valve
IEEE Transactions on Control Systems Technology, 2007This brief considers the control of solenoid valve actuators used for gas exchange in internal combustion engines. Although solenoid valves offer performance benefits over traditional camshaft-based valve systems, maintaining low impact velocity is a critical performance requirement.

Flatness-based hierarchical control of the PM synchronous motor
Proceedings of the 2004 American Control Conference, 2004The paper describes a flatness-based control scheme for the permanent magnet synchronous motor. A hierarchical control is developed and the scheme is shown to be compatible with the flatness properties via a detailed time-scale analysis. The proposed control strategy also achieves copper loss minimization at all operating points.

Nonlinear Vehicle Dynamics Control - A Flatness Based Approach
Proceedings of the 44th IEEE Conference on Decision and Control, 2006The central issue of this contribution is the discussion of the differential flatness of the planar holonomic bicycle model. The components of a flat output are given as the lateral and the longitudinal velocity component of a distinguished point located on the longitudinal axis of the vehicle. This property is shown for the front-, rear- and all-wheel

A differential flatness based model predictive control approach
2012 IEEE International Conference on Control Applications, 2012In this contribution a novel extension to model predictive control for a certain class of input affine nonlinear systems is proposed, which satisfy the property of differential flatness and are of minimum phase. By feedforward linearization of the nonlinear system via a flatness based control law, the problem of nonlinear model predictive control is ...
