System and method for virtual sensing based on empirical ensemble of gas emissions

摘要

An empirical ensemble based virtual sensor system (VS) for the estimation of an amount of a gas (G) resulting from a combustion process (CP) comprising two or more empirical models (NN1, NN2, . . . , NNn). The amount of gas (G) is estimated in each of the empirical models (NN1, NN2, . . . , NNn), and a combination function (f) combines the results from the empirical models (NN1, NN2, . . . , NNn) to provide a combined estimate for the amount of gas (G) that is more accurate than the estimated amount of gas from each of the individual empirical models (y1, y2, . . . , ym). The total performance of the virtual sensor system (VS) may be increased by increasing the number of empirical models (y1, y2, . . . , ym).
