Composite Active Disturbance Rejection Controller For Magnetic Levitation System

Abstract

 A composite Active Disturbance Rejection Controller (ADRC) and Proportional Integral Derivative (PID) controller are designed and implemented for the stabilization of steel ball in a magnetic levitation (MAGLEV) system. The performance of the two controllers are analysed under two scenarios namely with and without disturbance. Simulation results prove the competence of composite ADRC and it outperforms conventional PID controller. Simulations were carried out in MATLAB.
