Nonlinear control of magnetization process

摘要

This paper presents a novel method for closed loop control of magnetization process using feedback linearization. A macroscopic model for the temporal evolution of magnetization is developed to account for the physical phenomena of domain rotation and hysteresis. A tracking control system using feedback linearization method is derived to assure zero steady state error between the flux density with respect to the desired. The proposed nonlinear control method is evaluated by simulation results for a desired constant setpoint and a sinusoidal function tracking.
