Abstract:

The development of new techniques for control of magnetic objects by external magnetic fields has been in constant improvement. These advancements range from the design and fabrication of magnetic nanoparticles to design and control of actuators that enable their manipulation. The ability to guide such magnetic objects at a distance without any direct mechanical contact is an attractive feature with great potential in medical applications. Magnetic fields are not distorted by their interaction with nonmagnetic materials, like those in the human body; and pose no harm to living tissues, which m

The subject of this thesis is the real-time implementation of algebraic derivative estimators as observers in nonlinear control of magnetic levitation systems. These estimators are based on operational calculus and implemented as FIR filters, resulting on a feasible real-time implementation. The algebraic method provide a fast, non-asymptotic state estimation. For the magnetic levitation systems, the algebraic estimators may replace the standard asymptotic observers assuring very good performance and robustness. To validate the estimators as observers in closed-loop control, several nonlinear

Abstract : Over the past three decades, various fields have witnessed a successful application of active magnetic bearing (AMB) systems. Their favorable features include supporting high-speed rotation, low power consumption, and rotor dynamics control.

Silver nanoparticles can be readily generated in micellar environments by ketyl radicals formed from the photoreduction of benzophenone in the presence of a suitable hydrogen donor. The yield of these ketyl radicals can be increased by extending the lifetime of the triplet radical pair through Zeeman splitting of the triplet sublevels in an externally applied magnetic field. This provides control over the rate of photogeneration of nanoparticles under very mild conditions. The rate of photogeneration can be monitored by the distinctive surface plasmon resonance absorption around 420 nm. In thi

Abstract:

Dissertação de mestrado integrado em Engenharia Eletrónica Industrial e Computadores<br>No âmbito deste trabalho foi desenvolvida uma solução inovadora e viável recorrendo a eletroímanes e ímanes permanentes para aplicações que utilizem sistemas de deslizamento, de forma a controlar a altura de levitação em função da carga. Tendo em conta o carater contínuo e permanente dos campos magnéticos gerados pelos ímanes permanentes, que não permitem controlo de acordo com a massa do corpo, foi necessária a implementação de um sistema hibrido baseado na utilização conjunta de eletroímanes. De fo

Abstract:

Nuclear magnetic resonance force microscopy (NMRFM) of a micron size sample of ammonium sulfate was performed by measuring the cantilever deflection produced by coupling the magnetic force to a mechanical cantilever at its resonance frequency. Spin-lattice and spin-spin relaxation measurements were obtained with our newly developed NMRFM probe. A system with more advanced positioning, acquisition and analysis has been fabricated. A new device in which a semi-automatic system performs nanoposition control, spin manipulation, dynamical measurements, and data analysis has been demonstrated to be

Abstract:

碩士<br>國立成功大學<br>物理學系<br>106<br>Complex oxides have caught significant attention for the development of the next-generation electronic devices due to their versatile functionalities and the tunability via the external stimuli, such as electrical and magnetic fields. To broaden the application of complex oxides, the new pathway to control the physical properties is on demand. Cobalt ferrite (CoFe2O4), a ferrimagnetic inverse spinel, is potential in the application of magnetic storage device because of its high magnetization and coercivity. In this study, we introduce the optical method to contro
