License information

The PIDrobust toolbox is published under the terms of the General Public License Version 3.

System requirements

  • Matlab 7.4.0 (R2007a) or higher
  • Control System Toolbox
  • Optimization Toolbox
  • Multi-Parametric Toolbox

    If the toolbox is not installed, PIDrobust will work, but the option "Check Uniqueness of Three-Points" cannot be activated.

Installation

  • Remove any previous copies of the PIDrobust toolbox.
  • Unzip the archive to a folder of your choice.
  • Add the 'pidrobust' folder to your Matlab path (see Matlab command 'addpath' or Matlab Menu File->Set Path).
  • (optional) Run the script 'copy_patchedallmargin_to_lti.m' in the 'pidrobust' folder to generate a patched version of the allmargin routine.

Usage

  • The main commands are

    - GUIpidspace : Start GUI for pidspace

    - pidspace : Calculation of all PID controller parameters fulfilling a certain cirterion.

  • See also the Examples-Menu in the GUIpidspace.
  • The toolbox is still under development.
