Interests: model predictive control; process modeling, simulation and optimization; efficient numerical algorithms; biomedical systems modeling and advanced control algorithms; multivariable system identification and performance monitoring; optimal robotic manipulation and locomotion.
The area of process control has changed significantly over the last few decades, in terms of methods, algorithms, and application domains. Cost and energy reduction needs have prompted process and control engineers to develop and adopt optimization-based control systems, which nowadays pervade many process industries. Advanced process control systems have optimization objectives to meet, not just regulation tasks to perform; to meet these objectives, a strong and delicate blend of advanced hardware (sensors and actuators), software (algorithms), and process knowledge (modeling) is required.
The Special Issue, "Process Control: Current Trends and Future Challenges" of the journal Processes, seeks contributions to assess the state-of-the-art and future challenges in the wide area of process control; topics include, but are not limited to: optimization-based control and estimation methods, distributed control architectures for plant-wide optimization, process monitoring, diagnosis and fault detection, process dynamic modeling and identification for advanced control systems, applications of advanced instrumentation, and soft sensors.
Papers involving industrial collaborations are particularly encouraged in order to provide the reader with a clear assessment of the current best practice, and to better understand which challenges are likely to be faced in the near future.

Title: Quality-by Design in Pharmaceuticals Freeze-drying: Optimization of the Operating Conditions of the Primary Drying Stage
Authors: Davide Fissore and Roberto Pisano
Affiliation: Dipartimento di Scienza Applicata e Tecnologia – Politecnico di Torino (Italy)
Abstract: The optimization of the primary drying stage in a pharmaceutical freeze-drying process is a challenging task, as drying time has to be minimized beside preserving product quality. Following the guidelines issued by US-FDA in 2004, and taking advantage of the various Process Analytical Technologies (PAT) that have been proposed in recent years to monitor a freeze-drying process, pharmaceutical manufacturers are moving from a quality-by-testing to a quality-by-design approach. In this framework, model-based tools for process design have been proposed, with the goal to identify the design space of the process. This paper addresses the case of process optimization when processing a product whose dried layer resistance, one of the key model parameters, is affected by the operating conditions. Few experiments are required to identify model parameters, and a simple and effective method to identify the design space (and to optimize the process) in this case is presented.

Title: Steady-State Identification Analysis of an Industrial Depropanizer Column

Abstract: This paper introduces a novel steady-state identi_cation (SSI) method based on the Auto-Regressive model with eXogenous inputs (ARX). This method allows the SSI with reduced tuning by analyzing the identi_ability properties of the system. In particular, the singularity of the model matrices is used as an index for steady-state determination. In this contribution, the novel steady-state identi_cation method is compared to other available techniques, namely the F-like test  and a polynomial-based  approach. All these methods are implemented for SSI of two di_erent cases. The _rst case corresponds to a literature non-linear CSTR example running at di_erent steady states. Then an industrial case considering real data from a depropanizer column from Petrobras S.A. is analyzed. The robustness of the techniques is veri_ed for the industrial case with di_erent operating conditions.
