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).

Differential flatness based full authority helicopter control design

Proceedings of the 38th IEEE Conference on Decision and Control (Cat. No.99CH36304), 2003
A full authority helicopter control design based on differential flatness is presented. The concept of outer flatness is deployed for the design. The position dynamics and attitude dynamics are treated as the outer and inner systems respectively. The proposed design is based on an approximate model which is differentially flat, and then modified for ...

Flatness based control of a parallel hybrid drivetrain

IFAC Proceedings Volumes, 2010
Abstract The main advantage of hybrid electric vehicles (HEV) is consumption reduction and minimization of exhaust emissions. Moreover, drivability can be increased in a HEV. Due to the electric machine in the drivetrain of a parallel HEV, it is possible to realize gear shifts without an intermission in the wheel torque and therefore to increase the ...

A differential flatness based model predictive control approach

2012 IEEE International Conference on Control Applications, 2012
In 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 ...

Flatness based control of three-phase boost rectifiers

2005 European Conference on Power Electronics and Applications, 2005
The flatness of the mathematical models of the three-phase three-wire and four-wire boost rectifiers is shown. Two trajectory planning algorithms are developed that enable fast voltage restoration after load steps by considering a load estimate. A load observer is suggested. Two tracking controllers are given. Simulations with a switched model show the

Flatness-based control of an hydro power plant

Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference, 2010
Power-frequency control constitutes an Ancillary Service provided by power plants for the electrical power system stability. In France, grid requirements impose a fast and stable dynamic response of generating units allocated to this service. For hydroelectric power plants with surge tank, these control performance can be difficult to guarantee for all

Flatness based design method for nonlinear control systems

2011 IEEE/SICE International Symposium on System Integration (SII), 2011
A lot of control design methods have been reported so far. Among them we focus on the flatness based method. This method seems promising because the nonlinear controllers can be constructed by means of a linear design approach, due to the flatness property.

Stability of Nonlinear Flatness Based Extended PID-Control

IFAC Proceedings Volumes, 2001
Abstract Stability and robustness of a specific nonlinear tracking control strategy are shown. The structure of the studied control law consists of the sum of a nominal input and a correction term calculated by an extended PID-controller. Thereby the nominal input is a direct result of the differential flatness property.
