A novel magnetic suspension platform is studied in this paper. Three sets of suspension apparatus is adopted to produce suspension force, each of which consists of the permanent magnet, the U shape yoke and suspension coils. Material of yoke is laminated transformer silicon steel (30ZH100).Material of Permanent magnet is Nd2Fe14B. The mathematical model of suspension was established by analyzing the force exerting on rotor. In view of the levitation system with multi-variable, nonlinear, strong coupling characteristics, ADRC is applied to realize decoupling and disturbance rejection. The rule of ADRC parameter setting was obtained through lots of simulations. The simulation and experimental results indicate this suspension altitude control system has better dynamic characteristics and robust. |
