modelPIDScale
Test model for PID controller with scaling of the control error
Information
Validation test for the block AixLib.Controls.OBC.CDL.Reals.PID with and without setting of the parameter that scales the control error.
The test has two combinations of a PID controller and a plant.
In PIDSca, the control error is scaled inside the controller, whereas
in the configuration that has PIDNoSca, the setpoint signal and the
measurement signal is scaled outside of the controller.
Both controllers and plants have the same trajectory, thereby validating that
the scaling is implemented correctly.
