Title Of Article :
Novel feeding strategy for adaptive control of bioreactor processes
Latin Abstract :
In this paper a novel feeding strategy is suggested for bioreactor processes. The strategy, referred to as
the modified linear feeding strategy (MLFS), is shown to overcome the disadvantages of the feedback
exponential feeding strategy and the linear feeding strategy, resulting in a fast response in substrate concentration
for a large range of values of initial conditions. It is also shown that one of the main features
of the MLFS is that it effectively decomposes the closed-loop system into a fast and a slow subsystem.
This property is used to prove that the control input cannot saturate in the case when an adaptive version
of MLFS is used to control the processes with Haldane kinetics. In the latter case, the MLFS is also
shown to effectively help in assuring the stability of the closed-loop system. Applications of the MLFS in
both nonadaptive and adaptive cases are illustrated through computer simulations.
