12.5. Simulink Functions

SIMULINK has a number of built-in functions to perform ratio, selective, and split-range control. Examples are shown here.

ProductCan be used for ratio control
MinMaxCan be used for high or low selection
SwitchCan be used for switching between alternatives
SaturationCan be used for split-range control, and controller saturation

An example SIMULINK block diagram to implement a split-range jacket temperature controller from Example 12.1 is shown in Figure 12-7. Since this has been formulated in deviation variable form, the output of the jacket temperature controller ranges from –50 to 50%. Saturation elements are used for the ...
