This work demonstrates the design and development of a magnetic levitation (MagLev) system that is able to control both position orientation levitated object. For control, pole placement method was exploited estimate parameters proportional integral derivative (PID) controller. In addition, MagLev constructed using pair electromagnets, two infrared (IR) receiver-emitter pairs servo motor allow ...

An innovative magnetically levitated system design is presented in this paper. The proof mass, used as the seismic detection components for gyroscopes, is levitated by the presented micro-coil actuator so that the concerns that mechanical fatigue, asymmetry and misalignments, which are inevitably present in the traditional mechanical springs design, can be ruled out. In addition, the limited ra...

The MAGLEV Transrapid is a kind of new type high speed train in the world which is levitated and guided over the track using electro magnetic forces. Because the electro magnets are unstable, they have to be controlled. Since 2002 the worldwide first commercial use of such a high speed train based on German technology is running successfully in Shanghai Pudong Airport, P.R.China. In this paper ...

In order to improve the performance of a magnetically levitated (maglev) axial flow blood pump, three-dimensional (3-D) finite element analysis (FEA) was used to optimize the design of a hybrid magnetic bearing (HMB). Radial, axial, and current stiffness of multiple design variations of the HMB were calculated using a 3-D FEA package and verified by experimental results. As compared with the or...

This paper is devoted to the development of an advanced controller for a maglev artificial heart: in particular, a magnetically levitated left ventricular assist device is studied and the disturbances from the natural heart are taken into account. The main goal is to define a control action able to reject dc as well as periodical disturbances from the control input in steady state. This is acco...

Real-Time Control Over Networks. (May 2006) Kun Ji, B. S., Tsinghua University, Beijing, China; M. S., Tsinghua University, Beijing, China Chair of Advisory Committee: Dr. Won-jong Kim A control system in which sensors, actuators, and controllers are interconnected over a communication network is called a networked control system (NCS). Enhanced computational capabilities and bandwidths in the ...

This paper reports the development of Metal-amplified Density Assays, or MADAs - a method of conducting quantitative or multiplexed assays, including immunoassays, by using Magnetic Levitation (MagLev) to measure metal-amplified changes in the density of beads labeled with biomolecules. The binding of target analytes (i.e. proteins, antibodies, antigens) to complementary ligands immobilized on ...
