摘要：
The reachability of a simple nonlinear fed-batch fermentation process model is investigated in this paper. It is shown that the known difficulties of controlling such processes are primarily caused by the fact that the rank of the reachability distribution is always less than the number of state variables. Furthermore, a co-ordinates transformation is calculated analytically that shows the nonlinear combination of the state variables which is independent of the input. The results of the reachability analysis and that of the co-ordinates transformation are independent of the source function in the system model. The results are extended to the four state variable non-isotherm case, and to nonlinear fed-batch chemical reactors with general reaction kinetics. Copyright (C) 2002 John Wiley Sons, Ltd.
