The application research of several methods in the ball mill pulverizing system

摘要

Aiming at the ball mill pulverizing system, the controller is designed using the auto-disturbance-rejection controller (ADRC) method, reversed-frame normalizing (RFN) method and H-infinite method by analysing the dynamic characteristics. The simulation results show that the three methods could overcome the multivariable disturbance and the coupling characteristics of the object with good anti-disturbance ability and robustness meeting the requirements of system control.
