Such new variable is tested by pattern recognition for saturated alcohol and ether, combined with block variables' orthogonal computation and canonical correlation ana.

Based on block variables thought, available information about classification was drawn from several series of classifers by orthogonal computation and canonical correlation analysis(CCA), the discriminant least square models were thus set up to classify these ether and alcohol samples.

For the temporal correlation, each frame was segmented into three kinds of regions according to block-featuring variant TL , and correlation in each region was analyzed.

To solve constraint control problem, this paper combines modular multivariable control and self rectifying controller, besides stair like control, to form a new multivariable self tuning controller.

From the point of constraint control, this paper constructs a new multivariable self tuning regulator combining modular multivariable control technique and self tuning regulator.
