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.
