Construction of Computer Controlled Bioreactor

Bioprocess automation is developing fast for the reasons of quality control, production cost reduction et. al.. Bioreactor is the central equipment of bioprocess. Construction of computer controlled bioreactor is need for bioprocess automation. In this research, a two level hierarchical structure computer control bioreactor system is designed and constructed. The lower level plays the major role of set-point feedback control of process variables and the higher level plays the major role of graphical human interface and biological mathematical model solution. This control system has advantages of high reliability and flexibility than the single level digital control system, and has plenty of functions and high practicality compared with a normal commercial one.
