“…The magnet configuration is chosen on the basis of required pole face area and the necessary window area to house the excitation coils. There are various magnet and rail geometries, that is, magnet with U and E profiles and various winding arrangements with flat and U-profile rails, as shown in Figure 5 [19,20]. In omega-shaped actuator, [21] four electromagnets are used.…”

Electromagnetic levitation is an important area of research. There is lot of applications of maglev in industry. Extensive research is going on for the last two decades throughout the world to design the latest form of the maglev system. Due to interdisciplinary nature, many aspects are still open in maglev research. The major components in an electromagnetic suspension system are (i) actuator, (ii) sensor, (iii) controller, and (iv) power amplifier. For the successful implementation for any maglev-based project, the basic knowledge of these components is necessary. In this manuscript, an extensive review of different components of electromagnetic levitation systems has been presented.

“…Magnetic levitation technology with frictionless movement has been used in many industrial systems including in high-speed maglev trains, frictionless bearings, electromagnetic cranes, levitation of wind tunnel models, vibration isolation of sensitive machinery, levitation of molten metal in induction furnaces, rocketguiding projects, levitation of metal slabs during manufacture and high-precision positioning of wafers in photolithography [1][2][3][4][5][6][7][8]. The technology under a feedback controller can ensure reliable and high-speed operations, but getting a high control performance is not easy with standard controllers due to open-loop unstable and highly nonlinear dynamics, and parameter uncertainties of the magnetic levitation plants.…”

Abstract. The effectiveness and applicability of magnetic levitation systems need precise feedback control designs. A cascade control approach consisting of sliding mode control plus sliding mode control (SMC plus SMC) is designed to solve position control problem and to provide a high control performance and robustness to the magnetic levitation plant. It is shown that the SMC plus SMC cascade controller is able to eliminate the effects of the inductance related uncertainties of the electromagnetic coil of the plant and achieve a robust and precise position control. Experimental and numerical results are provided to validate the effectiveness and feasibility of the method.

“…One can easily verify that the satisfies LfV(z,Sy) = 0 and LgV(z,6y) = Sy with the storage function v(z,6y) = wo(z) + (1/2)Sy2 = (1/2)z2 + (1/2)6y2, thus the closed loop system (15) is looseless (see [l] for more details). Since system (15) It is possible to design a strategy for regulation of the sphere position at an equilibrium point that takes advantage of the passivity property induced by the static feedback (14).…”

This work deals with the modeling and control of a magnetic levitation system. A nonlinear model, valid for a certain region of interest, is obtained by considering the compensation of the gravity force. A control strategy is design for the system that it is based on the concept of passivity, in particular by establishing the equivalence of the levitation system to a passive one and considering a position regulation strategy. Real time experiments were carried out to show the performance of the proposed control scheme.
