Effect of open- or closed-loop deflection control on the measured flexural toughness of fiber reinforced concrete (FRC) was investigated. Third-point loading tests were performed as per ASTM C1609M on several high strength concrete mixtures containing low volume fractions of single, double and triple-fiber blends.

One of the significant difference between the open loop and closed loop control system is that in an open loop system the desired output does not depend on the control action. While in the closed loop system the desired output depends on the control action of the system. The other differences between the open and closed loop system are shown below in the comparison chart.

in Closed Loop The "open" or tower circuit is different from the "closed" loop circuit. The difference is that all static heads are not cancellable. In the open piping circuit, the pump must raise fluid from a low reference level to a higher level; this requires pump work and open statics becomes an important consideration for pump ...

A great many open and closed loop controls can be found in the cement production, however, the proper control of the operation-triplet, i.e., proportioning — burning — grinding can ensure that the overall control aim is reached, and that the other controls are auxiliary ones. Therefore, these three areas are investigated next.
