Data-Driven Control Strategies In Upstream Bioprocessing: Integrating Analytics, Automation, And Adaptive Systems

Abstract

Driven by process analytical technology (PAT), advanced sensor instrumentation, and multivariate statistical modeling, data-driven control strategies have opened up the next generation of biological manufacturing, enabling unprecedented levels of real-time process observation, comprehension, and governance in upstream bioprocessing through continuous, high-resolution perception into key process parameters and quality attributes. Control architectures, ranging from basic feedback control to complex model predictive control, translate these analytics-driven results into coordinated and timed actions for the process equipment to balance the highly nonlinear and multivariable nature of cell culture processes. Soft sensors, anomaly detection, and predictive quality models, as well as adaptive control policies, have been developed from historical and real-time process data using machine learning-based approaches. The advent of digital twin software for biomanufacturing will lead to mechanistic models and data analysis being integrated into dynamic digital twins that can be optimized and, subsequently, scaled up and deployed in real-time in response to any deviations throughout the lifecycle of the bioprocess. Therefore, these platforms are gradually leading biomanufacturing towards more adaptive and autonomous biomanufacturing environments with higher process consistency, product quality, and operational efficiency. Issues with data integrity, model life cycle governance, workforce capability development, and regulatory acceptance of automated decision-making systems must be addressed if the potential is to be realized on a commercially viable basis. The continual maturation of integrated data-driven control architectures will become the norm for the biologics manufacturing of the future, driving new standards for process performance and quality assurance.
