This is the demo file for September 2009 MathWorks webinar and November 2009 MATLAB Digest article "PID Control Design Made Easy":
The demo shows the PID Controller block in Simulink and PID Tuner in Simulink Control Design:
PID Controller is used to control a four bar linkage mechanism modeled in SimMechanics.
To see how to tune the PID Controller, please see the webinar, read the MATLAB Digest article, and visit the page with resources on PID Control Design and Tuning: http://www.mathworks.com/discovery/pid-control.html
Added a link to the PID resource page:http://www.mathworks.com/discovery/pid-control.html
Updated the description and title
Fixed the broken links issues.
Fixed the typos in text.
