Abstract

In order to reduce the power consumption of magnetic suspension system, a magnetic suspension system using variable the flux path control method was put forwarded.Its feasibility was verified by using FEA, and a dynamical model was developed.To stabilize the system, a robust control model was established and a corresponding status feedback γ-suboptimal H∞ robust controller was designed according to the H∞  robust control theory based on the LMI.The suspension characteristics were analyzed using numerical simulations and experiments.The results show that the suspension system can realize the energy saving of the suspension, track the input displacement signal, restrain disturbance forces, solve the problem of system instability caused by uncertain parameters and disturbances and ensure the robustness of system.
