Abstract

Based on magnetic levitation ball system, we designed a PID controller which can control magnetic levitation ball. On the basis of analyzing the magnetic suspension system structure and working principle, established a mathematical model of magnetic suspension ball control system and designed a PID controller. Using MATLAB to simulate and control the magnetic suspension ball control system timely, and get better control parameters. The result shows that the proposed method is effective.

Key words：Magnetic suspension system; PID controller; Matlab simulation
