Advances in genetic engineering have generated great interest in biote
chnology systems. Modern fermentation processes have a more scientific
basis and can be optimized more quickly by utilizing instrumentation
and control technology that permits increasing yield and product quali
ty. The automation technology, to a large extent, can determine the de
gree of success of growing microorganisms. The automation system in mo
dern biotechnology facilities includes a number of leading technologie
s such as sensors, indicators, data acquisition, distributed control,
programmable control, communications, data base management, on-line da
ta analysis techniques and application software. Modern computer syste
ms have made fermentation processes easier and more accurate by perfor
ming tasks such as on-line analysis, statistical process control and s
upervisory control, while microprocessor-based distributed process con
trollers perform direct digital control, batch and sequencing control.
This paper addresses technical issues related to the development of i
nstrumentation and control systems that integrate these technologies t
hrough methodologies that permit the timely generation of the document
ation and drawings that specify the control system for procurement, in
stallation, commissioning, validation and operation.
