In this paper, the magnetic levitation system that uses a Hall effect sensor as a detection element and a permanent magnet as the levitated object, is researched experimentally. The closed-loop frequency response of the system is measured under different power supply voltages. The open-loop frequency response data of the system are obtained from the closed-loop frequency response data. Based on the obtained open-loop frequency response data, the optimization methods are used to obtain a parametric open-loop transfer function model, which helps to understand the dynamic properties of this type of magnetic levitation system. A compensator based on the obtained frequency response is designed. The actual operation shows that the designed compensator can effectively improve the performance of the system.
