Design of High Stability Margin Controller for Magnetic Suspension Motor
Magnetic levitation high-speed motors are often used in harsh industrial environments.The exter-nal environment and the imbalance of the rotor can easily cause interference to the magnetic bearing control system,resulting in system parameter perturbations.This requires the magnetic bearing controller to have a large stability margin and strong robustness,so as not to cause rotor instability due to parameter perturbations at high speeds.Firstly,the article established the mathematical models for the magnetic levitation system;Then,based on the channel decentralized control strategy,the controller was designed to maintain phase an-gle margin,which was compatible with the fast,stable,and high-precision steady-state error indicators of the closed-loop system.
