In order to minimize the process delay between control action changes to correct any undesired changes during process operation, we propose an alternative approach that integrates a novel machine learning based process monitoring framework with multi-parametric Model Predictive Controller (mp-MPC) design. Central to the process monitoring framework are novel theoretical and algorithmic developments in SVM-based feature selection [3-5] which encapsulates highly nonlinear relationships between features, thus improves fault detection model accuracy. On the other hand, multi-parametric Model Predictive Controller (mp-MPC) design via the Parametric Optimization and Control (PAROC) framework [6] enables having the offline map of explicit fault-aware control strategies. Here, the control strategies are affine functions of the system states and the magnitude of the detected fault. By integrating a novel and accurate data-driven monitoring framework and explicit fault-aware control technology, we aim to produce an adaptive approach for smart operation where rapid switches between a priori mapped control action strategies are enabled by continuous monitoring information of the chemical processes. The results will be presented through the penicillin production benchmark model [7].
