Abstract: The object of this paper is to investigate the dynamics of the closed loop of a cement mill and to introduce an approach for tunning robust PID controllers. Based on the analyze of the dynamic behavior of the cement mill, a robust PID controller is designed and then simulated.

In this paper a model reference control of a cement raw mill with multirate sampling is presented and some practical results discussed. In the next section the controlled process is briefly analyzbed and the main control problems are pointed out. ... The mill closed loop control is a simple proportional control.
