For uniform irradiation in ICF, a non-contact target is the key technology. A magnetic suspension system is one of the best ways. In this paper a magnetic suspension system is primarily designed and a phase-lead controller operating in the inner loop is utilized to stabilize the magnetic suspension system. In simulation, the ball vibrates slightly in the first 10 ms, then stabilizes gradually and eventually reaches the set position. The result shows that the system can work stably and the magnetic suspension for ICF target is feasible.
