Control Performance: An Imperative for Safety
This paper explains the link between control performance and safety, reviewing the minimum requirements for effective control system operation.
When handling dangerous energy, chemical, and mechanical hazards, the automated control system is the first layer of safety. It can respond more quickly, predictably, and repeatedly than a human operator. Yet few plants are measuring the performance of the control system and its resulting effect on safety. This means that the control system may not be capable of meeting its design requirements, and could fail in the face of a serious safety hazard.
