Data-Driven Optimization Control for Safety
2014-10-8 Abstract: Grinding particle size (GPS) of a hematite grinding process (HGP) is characteristic of sensitivity to disturbances of ore hardness and size distribution, difficulty in establishing a mathematic model, and absence of measurement, which make the existing operational optimization and control approaches difficult to be applied. This leads to that it is always difficult to obtain a proper
