Abstract

This study investigates the impact of Fractional Order PID (FOPID) controllers in stabilizing high-speed rotating shafts supported by Active Magnetic Bearings (AMB). The vibrations in parallel and conical modes arise due to gyroscopic effects and need careful decoupling. Conventional Integer Order PID (IOPID) controllers have been widely implemented but may not be sufficient for complex AMB dynamics. To enhance stability, this research integrates the FOPID controller within a decoupled control structure and evaluates its performance using a centrifugal compressor with a five-degree-of-freedom AMB system. Comparative experimental results highlight the superiority of FOPID over IOPID, demonstrating improved system control capabilities.
