Split Range Control

SPLIT-RANGE CONTROL Unlike the cascade and selective control schemes the split-range control configuration has one measurement only (controlled output) and more than one manipulaled variable. Since there is only one controlled output, we have only one control signal, which is thus split into several parts, each affecting one of the available manipulations. In other words, we can control a single process output by coordinating the actions of several manipulated variables all of which have the same effect on the controlled output .Such systems are not very common in biochemical processes but provide added safety and operational optimality whenever necessary, as the following examples demonstrate. Reference: learning material and videos of this chapter are prepared from the text book "Chemical process control : An introduction to theory and practice by George Stephanopoulos".
