Abstract

To solve the possible lateral displacement caused by external disturbance forces in the novel Detent-force-based Magnetic Suspension System (DMSS), the lateral air gap control system with a differential control strategy of dual-electromagnet is studied. A dual-electromagnet model with a lateral air gap control system is established, and a fuzzy PID controller is designed based on fuzzy control theory, realizing online self-tuning of the PID parameters. The simulation result shows that the fuzzy PID controller has better dynamic and anti-jamming performance. It provides an important theoretical basis for the application of the lateral air gap control system in the actual magnetic levitation systems.
