Other AbstractThe invention relates to the technical field of cement production, and particularly relates to a soft measurement method for f-CaO content of a cement clinker. The soft measurement method comprises the steps of selecting three modulus values of raw materials, fineness of the raw materials, heat value of coal powder, ash content of the coal powder, feeding amount of the raw materials, an outlet temperature of a decomposing furnace, a kiln current and a grate bed pressure of a grate cooler as auxiliary variables removing outlers, filtering and standardizing a data set of the acquired auxiliary variables to form an input data set categorizing the input data set, establishing a partial least squares sub-model and a weight model for each category respectively then carrying out weighted average on the output of each sub-model to obtain a final soft measurement result and rectifying a soft measurement model by using a long-term correction method. The soft measurement method for can measure the f-CaO content of the cement clinker which is difficult to measure on-line and very important, allowing the implementation of advanced control for a cement clinker burning process to be possible.
