The paper presents a mathematical model and its Matlab/Simulink realization for ball mill coal-pulverizing system (BMCPS). Based on the analysis of mass and energy balance, the physical models for all control-related sub-processes of BMCPS are developed respectively. Then the integrated dynamic mathematic model is constructed with Matlab/Simulink. Validation using the archived data from a power plant...
A control-oriented dynamic model for a ball mill coal-pulverizing system (BMCPS) has been developed by using mechanism analysis and experiment identification. The nonlinear equations are obtained based on simplified physical model and previous efforts in BMCPS modeling. Through computation of known physical values, identification of grouped coefficients, and heuristic adjustments, the model parameters...
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 difference...
