Modelica library for generating stochastic signals to be included in the Modelica Standard Library.
This library contains standard models for generating random numbers in Modelica. It is intended to include this set of models in the Modelica Standard Library (MSL). More advanced noise features building on this library can be found in the AdvancedNoise library.
The library contains the following elements:
- a standard sampled noise source using the xorshift random number generator suite
- some commonly used probability distributions
- some statistical analysis blocks
Main features of the elements provided are:
- statistical quality of the random numbers by using the xorshift suite
- reproducability of the random sequences by providing a global and a local seed
- versatility by replaceable probability distributions for the generated noise
- mathematically correct statistical properties by using standard procedures only
Potential applications of the provided elements are:
- correctly modeling sensor noise by using the provided distributions
- stochastic excitations such as turbulence by filtering band-limited white noise
- any other application by providing easy-to-use basic functions.
The master branch of this library is currently reviewed for inclusion in the MSL.
The original version of this library was released after the Modelica conference in 2014:
