A visual programming environment for bioprocess control.

The paper introduces the use of a visual programming environment (LabVIEW) to program custom control functions for bioprocess research. The time taken for a bioprocess scientist to program new functions compared well with typical times expected for experienced programmers using conventional languages. Experienced LabVIEW programmers will develop applications significantly faster. The package described was flexible, easy to use and was ideally suited to developing new applications for control of bioprocesses. It was demonstrated with the development of a system to control specific growth rate in a fed-batch culture.
