Optimal decoupling control method and its application

Finally, for the decoupled system, the optimal tracking control method is used. It is proved that the decoupling control is optimal for a certain performance index. Simulations on a ball mill coal-pulverizing system are conducted. The results show the effectiveness and superiority of the proposed method as compared with the conventional optimal quadratic tracking (LQT) control method.Ball Milling - University of Massachusetts Boston,Ball milling (A) or stirring (B) H R Entry R= Method t/h Yield% anti/syn ee% 1 4-NO 2 A 5.5 99 89:11 94 2 4-NO 2 B 24 95 89:11 94 3 3-NO 2 A 7 94 88:12 >99 4 3-NO 2 B 16 89 82:18 98 5 2-NO 2 A 7 97 93:7 97 6 2-NO 2 B 36 89 91:9 97Grinding control strategy on the conventional milling,,the control loop will attempt to add water to Cyclone 1 sump to achieve a particle size of 15%+ 300 µm. If the hardness of the ore increases, the particle size in the mill discharge from ball mill 1 will increase. With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase. This will decrease the ratio, and hence
