Control of Magnetic Suspension Linear Feed System

Abstract:

A magnetic suspension linear feed device has been introduced in this paper, it is consist of linear motion and suspension parts. The mathematical model of suspension system is modeled. Aiming at the suspension part which is an nonlinear and strong coupling system, the auto-disturbance rejection controller (ADRC) is used. The inner disturbance and outside disturbance is observed and compensated, the result of simulation indicates the suspension control A magnetic suspension linear feed device has been introduced in this paper, it is consist of linear motion and suspension parts. The mathematical model of suspension system is modeled. Aiming at the suspension part which is an nonlinear and strong coupling system, the auto-disturbance rejection controller (ADRC) is used. The inner disturbance and outside disturbance is observed and compensated, the result of simulation indicates the suspension control has better dynamic, static and robust characters by using the auto-disturbance rejection controller.
