File Information
Description

The main objective of the tool is to provide better program support for design and simulation of nonlinear control systems in MATLAB/Simulink environment. It is encapsulated as a Simulink library, although besides function blocks designed for Simulink it also contains some applications designed directly for MATLAB and ready-made demo-simulations composed of the function blocks.

The NelinSys tool can help you with:
* phase plane analysis of nonlinear control systems
* analysis of limit cycles via harmonic balance (two-characteristics method)
* exact linearization control design and simulation
* gain scheduling control design and simulation

The NelinSys tool takes advantage of:
* MATLAB 5.2
* Simulink 2.2
* Symbolic Math Toolbox
* collaboration of above tools

The NelinSys tool might be useful in:
* education: various university courses on nonlinear control
* research: software for computer aided control design
* applications: everywhere where nonlinear control is employed

More information is available at http://www.kar.elf.stuba.sk/~mondera/NelinSys/ along with newer versions of the tool.
Required Products Control System Toolbox
Symbolic Math Toolbox
Simulink
MATLAB release MATLAB 5.2 (R10)
Other requirements The tool is optimized for use with MATLAB 5.2 / Simulink 2.2 but it was successfully tested to work with MATLAB 6.5 (R13) and MATLAB 7.0 (R14), too. Symbolic Math Toolbox is required, Control System Toolbox is recommended.

Updates
23 Jun 2005

For some odd reason my file was included in wrong category - "Image Processing: GUI, Display, Annotation" instead of "Controls and Systems Modeling: Control Design". With this update I'd like to correct that (there are no modifications to the files)
19 Sep 2005

Minor changes to the documentation - some help files that were in Slovak are now in English.

Minor fix. This update improves compatibility with higher versions of MATLAB, particularly MATLAB 6.5 (R13). Nevertheless, the NelinSys tool still works best with MATLAB 5.2.
24 Jul 2006

Compatibility fix. This update makes NelinSys compatible with higher versions of MATLAB. It was successfully tested to work with MATLAB 6.5 (R13) and MATLAB 7.0 (R14) and in all probability it also works with any other version between 5.2 and 7.0.

Licence update - in order to comply with the new MATLAB Central's licensing policy, the licence under which NelinSys is offered here (and only here) was changed from GPL to BSD. No functionality changes have been made to the files.
