identification

quickident is a powerful tool for computing a LTI model from experimental data (LTI: Linear Time Invariant).

Major features:

SISO, SIMO, MISO and MIMO models;
Closed loop identification
Intuitive graphical user interface

Other interesting features:

high numerical robustness, due to developpement of special algorithms;
delay identification in continuous and discrete time;
automatic identification of numerous configurations (order, degrees...). Results are then sorted by quality;
support for a large range of ASCII data files;
automatic data test and preprocess (bad data, offsets...);
model and controller reduction tool included;
two versions available: a Matlab toolbox or an executable version for Windows.

model reduction

modelreduction tool is a powerful software for model or controller reduction.

Major features:

Stable or unstable systems are supported;
Time horizon for reduction;
Intuitive graphical user interface;

Other interesting features:

high numerical robustness, due to developpement of special algorithms;
automatic redution for all possible orders. Results are then sorted by quality;
validation data can be imported to validate your model;
two versions available: a Matlab toolbox or an executable version for Windows.

This software is included for free in quickident.

Guaranteed numerical computations

Acsysteme Interval Toolbox is a powerful toolbox for Matlab that enables you to solve problems that were believed to be unreachable by numerical methods:

Global and guaranteed optimization;
Proof of the stability of a control loop over a parametric domain;
Find stability domain of a controller;
Guaranteed non linear equations and inequations solving, with or without equality/inequality constraints;
Graphical tools for displaying results in 1D and 2D.
