STINS: A Matlab tool for Stable Identification
of Nonlinear systems via Semidefinite programming
STINS (Stable Identification of Nonlinear
systems via Semidefinite programming) is
a Matlab implementation of our SYSID
approach for identifying stable nonlinear dynamical
models, as described in "Compact Modeling of Nonlinear Analog Circuits
using System Identification via Semidefinite Programming
and Incremental Stability Certification" by myself and others,
in IEEE Transactions on Computer-Aided Design of Integrated Circuits
and Systems, 2010. This software is a sample implementation that
identified input-output discrete-time models.
In STINS, a user provides as input to the software
training data input-output
signal pairs and a set of parameters describing
a rational model to be identified,
and the software returns a set of coefficients
defining a stable model of the specified complexity.
