emgr - Empirical Gramian Framework.
Empirical gramians can be computed for linear and nonlinear control systems for purposes of model order reduction or system identification.
The emgr framework is a compact open source toolbox for gramian-based model reduction and compatible with OCTAVE and MATLAB.
Features
emgr encompasses six types of gramians:
- Empirical Controllability Gramian
- Empirical Observability Gramian
- Empirical Cross Gramian
- Empirical Sensitivity Gramian
- Empirical Identifiability Gramian
- Empirical Joint Gramian
with sample implementations for:
- Balanced Truncation
- Direct Truncation
- Parameter Identification
- Parameter Reduction
- Combined Reduction
- Inverse Problems
