Description
In this example have been tested the tracking mode of the integral controller.
The process to be controlled has the following transfer function
Y(s) (1+15s)
---- = ----------------
U(s) (1+10s)(1+2s)
There are two processes:
- with a I controller,
- and a I controller with tracking mode
The output signal of the process controlled without tracking is the red line, while the green line is the
output of the process controlled with the tracking mode.
The CS of the controller becomes equal to the track reference signal TR when the Track Switch signal becomes true.
Discrete time
If the model parameter Ts is >=0 the continuous time controllers are
replaced by their discrete time versions.
The effect of various discretisation method can be studied.
