sssMOR, the sparse state space and Model Order Reduction toolbox, is an open-source MATLAB toolbox for the analysis and reduction of large-scale linear models, developed at the Chair of Automatic Control at TU Munich.
It can be seen as a natural extension of MATLAB's Control System Toolbox allowing to extend the analysis and control design to systems represented by large-scale models.
Features
sssMOR includes the sss toolbox which can be used to...
- ...define state-space models in MATLAB while preserving the sparsity of the system matrices. This allows a definition of models up to a state-space dimension of 108.
- ...exploit sparsity in the analysis of large-scale models with functions such as bode, impulse, step, lsim, norm, ...
- ...manipulate state-space models through additions, subtractions, multiplications, connections, truncations, ...
In addition, sssMOR includes...
- ...classical reduction methods such as modal truncation, Rational Krylov Method, Balanced Truncation, Approximate Balancing
- ...state-of-the-art reduction methods such as isrk, Iterative Rational Krylov Method, icop, cure, spark, cirka,...
- ...a Graphical User Interface (GUI)
sssMOR is compatible to MESS for the low-rank approximative solution of Lyapunov equations, e.g. within the functions norm and tbr.
The toolbox comes with a full MATLAB documentation as well as demos and tutorials. By signing up to our mailing list you can stay up-to-date with new releases.
A brief introduction to the toolbox is given in the paper [1], as well as in following poster:
