“…The eddy currents, in conjunction with the magnetic field, create a damping force. Publications in literature provide semi-analytical and analytical solutions for eddy currents and electromagnetic damping [7][8][9][10][11]. Few publications apply single or multiple layers of current mirrors to mimic the finiteness of the conductor [12], whereas others assume periodicity in the permanent magnet (PM) array [13].…”

This paper describes the optimisation of the eddy current damping, applied in a passive tuned mass damper (TMD). A semi-analytical model based on scalar potential formulation is extended for different permanent magnet (PM) topologies. Optimal design parameters are acquired by particle swarm optimisation. A 3-DoF mechanical model is presented to predict the quality reduction factor of the TMD. Measurements are performed for validating the semi-analytical model. Furthermore, an experiment is carried out to test a TMD with two optimal PM topologies for sinusoidal excitations.

“…The main drawback of these controllers is that symmetric constraints like stability conditions, decay rate conditions, disturbance rejection and eddy-current based force [8]- [9] due to the motion of the levitated object are not taken into consideration. In this paper, a linear matrix inequality based fuzzy controller is [12] proposed to reduce vibration in the object.…”

Magnetic levitation (Maglev) is becoming a popular transportation topic all around the globe. Maglev systems have been successfully implemented in many applications such as frictionless bearings, high-speed maglev trains, and fast tool servo systems. Due to the features of the instability and nonlinearity of the maglev system, the design of controllers for a maglev system is a difficult task. Literature shows, many authors have proposed various controllers to stabilize the position of the object in the air. The main drawback of these controllers is that symmetric constraints like stability conditions, decay rate conditions, disturbance rejection and eddy-current based force due to the motion of the levitated object are not taken into consideration. In this paper, a linear matrix inequality based fuzzy controller is proposed to reduce vibration in the object. The efficacy of the proposed controller tests on a maglev system considering symmetric constraints and the eddy current based force.
