Review of control and fault diagnosis methods

2015-8-1  The literatures,,,,,,,,,consider decoupling in ball mills with exhauster, where the major controlled variables include the outlet temperature, inlet negative pressure, and the pressure difference; while the manipulated variables are the opening of hot air gate, recycle air gate, and the feeder speed. There exists a very strong coupling among these loops, mainly between the temperature and the inlet negative pressure
