Neural network modeling and control of cement mills using ...
Abstract It is well known that the major cause of instability in industrial cement ball mills is the so-called plugging phenomenon. A novel neural network adaptive control scheme for cement milling circuits that is able to fully prevent the mill from plugging is presented. Estimates of the one-step-ahead errors in control signals are calculated through a neural predictive model and used for ...

Therefore, a fuzzy controller has been designed to use the expert knowledge of the operators for disturbedprocess control. Also, a self-tuning algorithm is incorporated for both on-line and o-line tuning of the fuzzy membership functions. This stone discusses the design of the fuzzy logic controller and its self-tuning.
New levels of performance for the cement industry
(Multiple mills can simultaneously discharge the same cement grade to the same con- veyor belt. However, belts can serve only one silo at a time and silos can be served by only one belt at a time.) Silo content: Only one ce- ment grade can be stored in a given silo. An example of rescheduling capability is shown in .
