چکیده
|
A key issue that affects a bioreactor performance and microorganism’s life is dissolved oxygen concentration# in order to reach maximum efficiency and productivity, controlling the oxygen level is of particular importance# because of the complexity of biological systems, most of the dynamic models representing them are nonlinear, so nonlinear controller and observer design methods must be used# since measuring some states of these systems are impossible, and because most of the controller design methods for nonlinear systems need all states' values, designing an observer is necessary# the designed controller should be able to reject all possible changes in parameters of the model as soon as possible, to prevent causing damages to the whole system# this paper aims at designing an appropriate input/output feedback linearization control, which handles parametric uncertainty and an extended kalman filter (ekf) observer to predict the dynamic behavior of the bioreactor#
