Abstract

Modeling, design, fabrication, and testing of single magnet, single axis DC attraction type levitation system (DCALS) has been presented in this chapter. The proposed two loop scheme is more attractive from control point of view than the mostly reported single loop position control. The order of the levitated system (plant) has been reduced by one due to the use of a controlled current source as the excitation of the magnet-coil. The analysis and design of the position controller becomes easier after considering the reduced order plant transfer function. The controllers have been designed based on classical control theory utilizing root-locus and frequency domain technique. The realization of the controller also becomes simple due to the use of analog circuits.
