Magnetic levitation control system has model perturbation and a variety of outside interference during operation, so, improving the robustness of magnetic levitation system is very important. This paper gives a mathematical model of magnetic levitation system;a fusion algorithm of H￥ and sliding-mode control is discussed;simulation is obtained by Matlab tool. The results show that the algorithm is robust to the uncertainty of the system on the matching and non-matching at the same time.
