The study on inverse system decoupling and PID control used in power magnetic beraing

摘要

In this paper, the coupling magnetic field model which the power magnetic bearing generated by interference between the rotation and levitation force is linear inverse system decoupling, and study PID control strategy on decoupling linearization system. According to the performance analysis and simulation of PID control system, it can be concluded that PID control system has quick response, high control precision, good control ability, and excellent robustness. It can be applied to project system.
