CM416 Project 2.
Due: January 24, 2000
PID Controller Tuning
Using the process "SYSTEM A" simulated through the link, http://www.chem.mtu.edu/~tbco/cm416/newpida.html,
apply the three tuning methods namely a) Ziegler-Nichols Method, b) Autotune
Relay Method and c) Cohen-Coon Method. ( Submit the plots used for the
determination of the controller parameters, as well the final controlled
process, for each method. )
Using the process "SYSTEM B" simulated through the link, http://www.chem.mtu.edu/~tbco/cm416/newpidb.html,
apply the tuning methods of Ziegler-Nichols and the Autotune Relay Method.
( Submit the plots used for the determination of the controller parameters,
as well the final controlled process, for each method. )
Using the process from SYSTEM B ( http://www.chem.mtu.edu/~tbco/cm416/newpidb.html
Under manual mode, set the input to 0.0 and wait for steady state.
Invoke a step change in the input to 1.0
After around 50 time units elapse, invoke an opposite step change in the
input to 0.0
After approximately 45 time units elapse, click on the PAUSE button. (You
will need a flat portion on the front of your output plot as shown below.)
Click the DATA button and the data window should appear.
Inside the data window, right click on your mouse to the SELECT ALL option.
Right click on your mouse to COPY to the clipboard.
Open an Excel spreadsheet and PASTE the contents from the clipboard.
Use the Excel spreadsheet (with SOLVER) to estimate a second order model
that would closely fit the data obtained from the previous step. (For a
quick tutorial, go to http://www.chem.mtu.edu/~tbco/cm416/modest.html).
(Submit at least the top part of your spreadsheet which shows the setup
and first few entries of the various columns.)
Write down the model which the SOLVER obtained. Also, show the plots of
the data together with the predicted/estimated values.
