Description of the software

iREG (Identification and Robust Digital Controller Design) is an interactive software, based on an easy to use graphical user interface (GUI) designed to provide reliable results for the identification and control of industrial single-input single-output (SISO) processes.

The program's capabilities are:

  • parametric identification and validation in open loop and in closed loop,
  • robust RST digital controller design based on sensitivity functions shaping,
  • controller order reduction,
  • computation of the parameters for continuous time PID controllers.

iREG offers also the possibility to work in a so called automatic mode, which gives the possibility to do open/closed loop identification and robust controller design based on predefined criteria so that very good results can be obtained easily with a minimum of user input.

There are various routines for identification in opened and closed loop. The controller design procedure is the combined pole placement with sensitivity functions shaping.

The theoretical background behind these procedures can be found in the book: Digital control systems, Springer, 2005, by Ioan-Dore Landau and Gianluca Zito.
