| Abstract: | On the basis of a theoretical research of partial least-squares regression spline transformation,the soft sensoring of aviation kerosene dry point of atmospheric distilation column of oil refining device was proposed.According to the collected samples,by using the auxiliary variables choosing method and the soft sensing method proposed,a soft sensoring model for predicting the dry point of aviation kerosene was set up.The simulation result shows that auxiliary variables chosen out by the proposed method car... |
