MAGNETIC LEVITATION SYSTEM
plant consists of an electromagnet, an optic position sensor, a
ferromagnetic sphere and a power interface.
Due to the spherical shape the measurement is nonlinear and needs
to be electronically or digitally linearised.

Velocity estimation
For fast nonlinear and unstable dynamical systems, such as magnetic
levitation, high quality of control is essential.
The ball velocity measurement is a di cult task.
Measurements of position and current is used for the velocity
estimatio ....etc

ABSTRACT

VEHICLE HANDLING, STABILITY,AND BIFURCATION ANALYSIS FOR NONLINEAR VEHICLE MODELS

Vehicle handling, stability, and bifurcation of equilibrium conditions were studied
using a state vector approach. The research provided a framework for an
improved method of vehicle handling assessment that included non-linear regions
of performance and transient behavior. Vehicle models under pure lateral slip,
constant velocity, and constant front steer were developed. Four-wheel, two-axle
vehicle models were evolved from si ....etc

Abstract

Magnetic servo levitation (MSL) is currently being investigated as an alternative to drive fast-tool servo systems that could overcome the range limitations inherent to piezoelectric driven devices while operating over a wide bandwidth. To control such systems, a feedback-linearized controller coupled with a Kalman filter has been previously described. Performance limitations that degrade tracking accuracy suggest the use of a more robust controller design approach, such as sliding-mode control. Current literature on sliding ....etc

Detecting Wide Lines Using Isotropic Nonlinear Filtering

Abstract:
Lines provide important information in images, and line detection is crucial in many applications. However, most of the existing algorithms focus only on the extraction of line positions, ignoring line thickness. This paper presents a novel wide line detector using an isotropic nonlinear filter. Unlike most existing edge and line detectors which use directional derivatives, our proposed wide line detector applies a nonlinear filter to ....etc

Abstract
Since the recent demonstration of chip-scale, siliconbased,
photonic devices, silicon photonics provides a viable and
promising platform for modern nonlinear optics. The development
and improvement of such devices are helped considerably by theoretical
predictions based on the solution of the underlying nonlinear
propagation equations. In this paper, we review the approximate
analytical tools that have been developed for analyzing active and
passive silicon waveguides. These analytical tools provide the much
needed phys ....etc
