Research on Levitation Control Method of Electromagnetic Levitation Ball System Based on Fuzzy-PID

摘要

In this paper, the electromagnetic levitation ball system is taken as the research object. The electromagnetic levitation ball controller combined with fuzzy control algorithm and conventional PID control algorithm is designed. Firstly, the basic principle of the electromagnetic levitation ball system is analyzed and the mathematical model is established. Then Based on the classical PID control model and fuzzy control algorithm, fuzzy inference of PID controller feedback parameters is realized to realize dynamic adjustment of feedback parameters of the PID controller. And the control algorithm is implanted into the DSP controller, then the loading and the unloading experiments are carried out. The experimental results show that the levitation controller has good static performance and better dynamic performance and robustness than conventional PID controller.
