3 Designing Controllers Using the Design Tool GUI

3-42

Constraint Softening Dialog Box

The Output constraints section lists the output limits and their relaxation bands. By

default, the output constraints are soft. Make the C

upper limit hard by entering a zero

as its relaxation band (as in Constraint Softening Dialog Box).

Select the Ysoft controller. Define a soft upper bound on C

by using the same settings

shown in Constraint Softening Dialog Box, but with a relaxation band of 100 instead of 0.

Simulate the three scenarios in the order they appear in the tree, i.e., None, Hard, Soft.

The resulting output responses appear in Constraint Softening Scenarios: 1 = None, 2 =

Hard, 3 = Soft.
