Process out-of-control cause diagnosis of coal preparation plant based on fuzzy pattern recognition

A new method of fuzzy pattern recognition is proposed considering the importance of eigenvector in recognizing fuzzy patterns. Aiming at the coal preparation process of the coal preparation plant, the eigenvector of process out-of-control cause is attained by using of the integrated environment and other application systems of CIMS. The method to diagnose process out-of-control cause is given based on fuzzy pattern recognition. The data flow diagram of carrying out the system is also given
