Loop priority based decentralized control for coal ball ...

Coal ball mill pulverizing system is a multiple-input multiple-output (MIMO) system characterized with strong couplings and disturbances. In the coal ball mill control system, the three loops possess different dynamics with remarkable lag times. In this paper, we proposed a mixed control scheme based on loop priority (namely the outlet temperature loop, the inlet pressure loop, the pressure ...
