Control of Non-Linear Process
Pre-Experimental Questions
Use the applet provided below to answer the following questions:
- Look at the open loop response. What are the ZN open loop settings
for this process?
- Now try these settings with different setpoints (0, 0.5, 1). Comment
on your results.
- Since the response changes when control is added, depending on the
setpoint, the controller will have to be tuned using the ZN closed loop
method. What controller settings do you evaluate for setpoints of 0,
0.5 and
1.0? Find optimal values for these setpoints.
The Process
The applet below shows the response of a process. It is possible for
you to insert controller parameters and see how the process responds.
The Answers
Once you have completed the experiment it is possible to compare your
answers with the right ones!
