PPR toolbox
Matlab functions and gui for the design of digital robust controllers.
PPR (robust poles placement) is a set of Matlab functions for the design of digital robust controllers.
Main features :
* linear single-input single-output (SISO) plant modelisation ;
* standard modelisation : external signals are also described to give an augmented plant ;
* closed-loop poles placement control with 2 high-level tuning parameters (HLTP) ;
* efficient control of the closed-loop performances through the HLTP ;
* 2 degrees of freedom controller : tracking and regulation have independant dynamics ;
* robust performances in tracking or regulation modes : models of the signals are included in the controller ;
* robust stability is achieved by HLTP tune with predictible results ;
* anti-windup digital implementation ;
* true digital design, no oversampling ;
* pole placement strategies linked to the state space feedback controller ;
* implicit internal simulation of the process maintains good performances on plant with large delay unlike PID controller.
Usage :
* Command line script ;
* Graphical user interface (ppr_gui invoked in the command window).
Documentation :
* examples and case studies are available in \ppr_example directory ;
* see also html files in \ppr_example directory.
Required installation :
* the PPR directories must be set in the Matlab path
* the Matlab CONTROL toolbox (8.0.1).
