Neural Network Trajectory Tracking Control on Electromagnetic Suspension Systems

open access: yesMathematics, 2023
A new adaptive-like neural control strategy for motion reference trajectory tracking for a nonlinear electromagnetic suspension dynamic system is introduced. Artificial neural networks, differential flatness and sliding modes are strategically integrated

A Test for Differential Flatness by Reduction to Single Input Systems [PDF]

open access: yes, 1995
For nonlinear control systems (p inputs), we present a test for flatness. The method consists of making an initial guess for p-1 of the flat outputs, which may involve parameters still to be determined.

In-domain control of a heat equation: an approach combining zero-dynamics inverse and differential flatness [PDF]

open access: yes, 2015
This paper addresses the set-point control problem of a heat equation with in-domain actuation. The proposed scheme is based on the framework of zero dynamics inverse combined with flat system control.

Tracking Control for Mobile Robots Considering the Dynamics of All Their Subsystems: Experimental Implementation

open access: yesComplexity, 2017
The trajectory tracking task in a wheeled mobile robot (WMR) is solved by proposing a three-level hierarchical controller that considers the mathematical model of the mechanical structure (differential drive WMR), actuators (DC motors), and power stage ...

Nonlinear Position Control Using Differential Flatness Concept with Load Torque Observer for Electro Hydraulic Actuators with Sinusoidal Load Torque

open access: yesMathematics, 2020
We propose a nonlinear position control using a differential flatness concept with a load torque observer to compensate for the sinusoidal load torque in electro-hydraulic actuators (EHAs) EHAs.

Accuracy of Surface Plate Measurements - General Purpose Software for Flatness Measurement [PDF]

open access: yes, 1990
Flatness departures of surface plates are generally obtained from straightness measurements of lines on the surface. A computer program has been developed for on-line measurement and evaluation, based on the simultaneous coupling of measurements in all ...

Null controllability of one-dimensional parabolic equations by the flatness approach [PDF]

open access: yes, 2015
We consider linear one-dimensional parabolic equations with space dependent coefficients that are only measurable and that may be degenerate or singular.Considering generalized Robin-Neumann boundary conditions at both extremities, we prove the null ...
