After reading this chapter the reader should be able to understand and develop ratio, selective and override control, and split-range control strategies. Ratio control is similar to feed-forward control, while selective and override control choose between alternative outputs or inputs. Split-range control chooses between two or more control valves to implement a manipulated input.
The major sections of this chapter are as follows:
12.2 Ratio Control
12.3 Selective and Override Control
12.4 Split-Range Control
12.5 SIMULINK Functions
