Realization of single side working mode of active magnetic bearings

  • It is difficult to provide an accuracy model for an AMB(active magnetic bearing) system due to the strong nonlinearity among magnetic force, the currents flowing in the coils and the displacements between the rotor and the AMBs. The bias currents in the coils increase the system power loss. For AMBs, higher stiffness and system stability in a larger displacement range could not be achieved at the same time. Magnetic force was considered as a controlled object and a component named magnetic force component with magnets and power amplifiers included was built to avoid nonlinearity of the model for the AMB system. With a base current of 0.2 A in the coils, high bearing stiffness was obtained when single side working mode of AMBs was achieved. To achieve higher stiffness and stability in a larger range at the same time, a fuzzy control method was used. Simulations and experiments show that a more accurate AMB model can be obtained with magnetic force component used; System power loss is reduced when single side working mode of AMBs is achieved and higher stiffness and stability in a larger range are achieved at the same time with the fuzzy control method used.
