Control in Cement Production ScienceDirect

1983-1-1  The other control loop regulates the specific surface area (s(t)) of the cement where set) is usually measured in every hour. The manipu­lated variable is c(t). Because of the very infrequent samplings this regulator may be an lone, however, a ST regulator to improve the dynamic properties can also be applied inde­pendently of the previous loop.

Five Methods for Controlling the Loop of Cement
