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. The simulation results confirm that the given approach provides high performances of the cement mill.
