Air Gap Control of the Novel Cross (+) Type 4-Pole MAGLEV Carrier System

Abstract

Mechanical non-contact carrier systems based on magnetic levitation (MAGLEV) are used in special transportation areas (clean rooms, chemical areas, etc.). Among these types of carriers, 4-pole hybrid electromagnetic systems (containing permanent magnets and electromagnets) stand out with their low energy consumption. The main problem of maglev carrier systems is their non-linear characteristics and unstable open-loop response. In this study, PID and I-PD controllers are designed for the air gap control of the new cross-type 4-pole mechanical contactless carrier system. Thus, the instability problem was overcome and the desired reference tracking for each degree of freedom was successfully carried out in simulation environments, and the results were compared.
