This paper contributes toward research on the control of magnetic levitation plant, representing a typical nonlinear unstable system that can be controlled by various methods. shows two approaches to solution controller design based different closed loop requirements. Starting from known linear plant model—the first method is two-step procedure. In step, transfer function modified get stable no...
The Levitron® is a popular toy that provides a unique and interesting demonstration of levitation using permanent magnets. It consists of a small, spinning magnetic top and a magnetic base plate. Stable levitation is possible because of a unique coupling of the magnetic forces and torques with the gyroscopic action of the top. A simple theory of its operation, using a general axisymmetric form ...
Abstract We present results obtained with an original hybrid set-up permitting to increase strongly the levitation force of Superconducting Magnetic Levitating (SML) systems. compare measurements carried out this a conventional one. investigate stability proposed system by measuring lateral (or restoring) force. show how calculate measured and forces from: (i) those in configuration (ii) repuls...
The Ring Trap 1 (RT-1) experiment has succeeded to produce a magnetospherelike high-beta (hot electron) plasma in a dipole magnetic field. Magnetic levitation of the super-conducting magnet, freeing it from mechanical supports, brought about significant improvement of plasma parameters (density, temperature, confinement time, etc.). The maximum (local) beta exceeds 0.1, which is primarily contr...
The paper deals with design of PID controller for unstable SISO systems in the frequency domain. The method is accomplished with performance specification in terms of phase margin and the modification of Neimark D-partition method which ensures desired phase margin. The practical application is illustrated by the PID controller design for the Magnetic Levitation Model.
