Application of soft constrained mpc to a cement mill circuit

Jan 01, 2010 The MPC uses soft constraints (soft MPC) to robustly address the large uncertainties present in models that can be identified for cement mill circuits. The uncertainties in the linear predictive model of the cement mill circuit stems from large variations and heterogeneities in the feed material as well as operational variations. These sources of

Dec 01, 2013 Abstract. In this paper, we develop a novel Model Predictive Controller (MPC) based on soft output constraints for regulation of a cement mill circuit. The MPC is first tested using cement mill simulation software and then on a real plant. The model for the MPC is obtained from step response experiments in the real plant

Rockwell Automation Pavilion8 Model Predictive Control (MPC) technology is an intelligence layer on top of automation systems that continuously drives the plant to achieve multiple business objectives—cost reductions, decreased emissions, consistent quality and production increases—in real time. Pavilion8's flexible hybrid modeling

Industrial Use of MPC • Initiated at Shell Oil and other refineries during late 70s. • The most applied advanced control technique in the process industries. • 4600worldwide installations + unknown # of “in-house” installations (Result of a survey in yr 1999). • Majority of applications (67%) are in refining and petrochemicals

For the selected CM, the power of the recycle elevator constitutes the process variable. Because the process value is a percentage of the maximum power of the elevator, the formula α x =100/ PV Max is used. For the given application PV Max =50 KW and, consequently, α x = 2. A first order filter is applied with T f = 180 s. By applying a step increase of the mill feed and

circuit product and is sent to the storage and dispatch silos, while the coarse material returns back to the cement mill to be ground again. Fig. 1 shows the grinding circuit layout of the industrial cement plant under study. The elements identified in the cement grinding circuit are: G20 is the ball mill; G24 is the dust collector of the ball

Stably controlling the pre-grinding process is paramount important for improving the operational efficiency and significantly reducing production costs in cement plants. Recognizing the complexity in both structure and operation of the pre-grinding process, this paper proposed a fuzzy and model predictive control system to stabilize and optimize the pre-grinding process
