Parameters self-adjusting fuzzy PID control in magnetic levitation system

The single freedom magnetic levitation ball system is the base of magnetic products, it is essential to study the magnetic levitation ball system. In this paper, preliminary researches are conducted by analyzing the magnetic levitation ball systempsilas working principle and deriving the mathematical model in detail. After linearizing and analyzing the non-linear model, we proposed a fuzzy PID controller based on MATLAB. Simulation results confirm that the controller dose indeed improve system performance.
