Abstract: ECP Model 730 magnetic levitation system is a typical non-linear experiment system. Due to uncertainties, non-linearities and coupling characteristics, the MIMO magnetic levitation system is more difficult to control than the SISO one. To solve the problem, friction identification experiment is performed and Stribeck curve of LuGre model is fit by genetic algorithm. The system is compensated for friction and decoupled. A new H∞ controller regarding friction uncertainties as system's input disturbance is designed to improve the control performance of this non-linear uncertain system. The effectiveness of the proposed controller is verified by practical bench tests.
