TLDR
In this article, a non-linear control law has been derived for the model-based PI controller for pH-controlled fed-batch neutralization process, and the simulation results show the superior performance and robustness of the model based PI controller over that of the conventional PI controller.Abstract:
The present study aims at bringing out the best features of model-based control, when applied to highly non-linear systems like pH-controlled fed-batch processes. For these processes, control of pH by conventional PID controller fails to provide satisfactory performance, because of the extreme non-linearity in the pH dynamics. In the present study, for a fed-batch neutralisation process, a non-linear control law has been derived for the model-based PI controller. Typical problems in process control like sampling, delay and perturbations in model parameters are addressed in this study using model-based control. The simulation results show the superior performance and robustness of the model-based PI controller over that of the conventional PI controller.read more

Model Based Controller and Linear Cascade Controller Applied to Fed Batch pH Process
TL;DR: In this article, a nonlinear control law has been derived for the model-based Proportional Integral controller for pH-controlled fed-batch neutralization process, and the simulation results show the superior performance and robustness of the model•based controller and linear cascade controller over that of the conventional Proproportional • Integral • Derivative controller.

Time-Optimal Control of Chemical Neutralization Process
TL;DR: In this article, the problem of optimal control of the chemical neutralization of acidic wastewater by means of lime water is formulated as a problem of time-optimal control, and it is shown that the timeoptimal process of chemical neutralisation is also optimal from the point of view of the accuracy of approaching to the neutral state.

GMC-fuzzy control of pH during enzymatic hydrolysis of cheese whey proteins
TL;DR: A hybrid GMC-fuzzy algorithm is proposed that presented a good performance in both regulatory and servo problems, and was coupled to the GMC architecture, taking into account process/model mismatches.
