Simple self-tuning type controllers Jbr nonlinear bacterial growth processes can be effective and their stability can be proven under mild conditions. Abstract-This paper suggests how nonlinear adaptive control of nonlinear bacterial growth systems could be performed. The process is described by a time-varying nonlinear model obtained from material balance(More)

In this paper we address the issue of minimal time optimal control of fedbatch reactor in presence of complex non monotonic kinetics, that can be typically characterized by the combination of two Haldane models. Global optimal trajectory results are provided on the basis of a numerical approach that considers smooth control inputs.
In this paper, we analyse some properties of the orthogonal collocation in the context of its use for reducing PDE (partial differential equations) chemical reactor models for numerical simulation and/or control design. The approximation of the first order derivatives is first considered and analysed with respect to the transfer of the stability properties(More)
