ORBIT - operating-regime-based modeling and identification toolkit

ORBIT is a MATLAB-based toolkit for black-box and grey-box modeling of non-linear dynamic systems. The model representation is based on multiple lo models valid in different operat ing regimes, that are smoothly blended into a global non-linear model. ORBIT is a computer-aided modeling environment that supports the interactive development of regime-based modelson the basis of a mixture of empirical data and prior knowledge (similar to Takagi-Sugeno-type fuzzy models). ORBIT contains functions for robust parameter identification, including constrained identification, regularization and Bayesian identification. These are functions for structure identification, including selection of the local model orders as well as decom positions into operating regimes that give a good fit to the data. Model validation, simulation, visualization and automatic code generation are also supported.
