Control Simulation of Active Magnetic Levitation Closed-loop PID System

Abstract

To realize “starting breeze, breeze powerâ€, using electromagnetic force to adjust the displacement of the magnetic suspension rotor of the wind turbine. Through the force analysis, the equation of motion of the magnetic suspension rotor is established. Closed loop PID control system is designed to obtain the transfer function of the closed loop system, according to the characteristic equation to determine the range of PID parameters, and then through the MATLAB Simulink simulation gives the specific PID parameters of the stable suspension. In order to lay a theoretical foundation for the stability control of magnetic levitation, a feasible method is provided for finding the PID parameters.
