| Abstract: | The selection of the secondary variable consists in the selection of the type, the number and the detect spot. It is the first step of the modeling for soft sensor, which relates directly to the quality of the soft sensor. This paper, aiming at the activate sludge, discusses from the point of view of the development and propagation of microorganism the influence and the correlation of all the factors which have affected the development and activities of microorganism and takes the magnitude of the influence and the complexity of coupling as a rule to select the secondary variable. The first selection is completed and the handpick of the secondary variable is discussed. |
