Controllers of PID type are by far the most widely used controllers in the chemical process industries. However, in many cases the controllers are not properly tuned resulting in a significant loss of performance. In order to counter this, new and simple tuning rules have been derived for single-loop PID controllers. These rules can be automated in order to assist with the design of PI and PID controllers. This software implements existing PI and PID tuning rules for processes that are either given in transfer function form or where data for the input-output behavior of the process is available. The controller tuning and evaluation of the closed-loop performance is performed interactively using a graphical user interface in order to enhance ease of use.


Installation Instructions:

  1. Download the software.
  2. Create a directory for the software.
  3. Extract the files into the newly created directory.
  4. Add the directory to the path in MATLAB.
  5. From within MATLAB, type 'PID_Design' to start the GUI.
