Model Predictive Control

Model Predictive Control (MPC) is an advanced control strategy that uses an explicit process model to predict the future response of a system. At each control interval, it solves an online optimization problem to determine the optimal control moves over a future horizon. In enterprise risk management, MPC serves as a proactive technical control. Its application in safety-critical systems is guided by functional safety standards like IEC 61511, which mandates robust controls to maintain processes within safe limits. By proactively managing complex multi-variable interactions and constraints, MPC helps achieve risk reduction targets, making it a key technology for Process Safety Management (PSM) and operational resilience.

MPC is applied to ensure business continuity by stabilizing production and reducing incident rates. Implementation involves three key steps: 1) Model Development & Validation, using historical data to build an accurate dynamic model; 2) Controller Design & Simulation, defining objectives and constraints and testing in a simulated environment; 3) Deployment & Monitoring, integrating with the existing control system and continuously tracking performance. This practice of continuous monitoring aligns with the performance evaluation clause of ISO 22301:2019. For example, a petrochemical firm reduced off-spec product by over 50% and energy use by 8%, significantly mitigating quality risks and enhancing operational resilience.

Taiwan enterprises face three main challenges: 1) High Initial Investment & Talent Gap: MPC requires significant capital and specialized engineers. The solution is a phased implementation, starting with high-return processes, and partnering with expert consultants. 2) Legacy System Integration: Older control systems may lack the necessary capabilities. The solution is to use flexible MPC platforms with standard protocols (e.g., OPC) and plan for gradual system upgrades. 3) Model Lifecycle Management: Process models degrade over time. The solution is to establish a formal model management process, including periodic re-validation and performance monitoring, which aligns with the principles of quality systems like ISO 9001:2015 for maintaining control resource suitability.
