controlSBML 1.1.3

Control analysis of SBML models

controlSBML

controlSBML is a python packag that assists with control engineering of biological systems that are characterized by models in the Systems Biology Markup Language (SBML), a community standard for representing models of biological models, especially chemical reaction networks. controlSBML provides the following:

• Read SBML models, viewing candidate inputs, and outputs, and running simulations.
• System identification, including the creation of (SISO) transfer function objects from the python control systems library
• Creating Antimony simulations of closed loop systems
• Design of closed loop systems

Examples of usage are in this directory

Installation

pip install controlSBML

To find the current version:
