PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL

2013-3-13  • Observations on the Control philosophy of the mills are: − The mill is being operated in manual mode most of the time − For control of fineness, only separator speed is being adjusted and no action on air flow through the separator − Water spray is being done into the 2nd Chamber of the mill even though the cement temperature is

Multivariable Nonlinear Control of Cement Mills

In this paper, multivariable nonlinear control strategies for a cement grinding circuit are studied. It is shown why nonlinear control is requested in order to deal with typical unmeasured perturbations (hardness change of the clinker) and subsequently two alternative strategies are compared: a nonlinear predictive controller and a state feedback controller based on Lyapunov design.

Nonlinear H-Infinity Control for Optimizing Cement ...

Nonlinear H-infinity control is developed aiming at optimizing the functioning of cement mills. The dynamic model of a cement mill is difficult to control due to its high nonlinearity and its multivariable structure. For this reason several control methods have been proven to be little efficient (e.g. MPC or NMPC). The cement mill's dynamic model is subjected to approximate linearization ...
