Abstract
This chapter is a sketch of 50years of developments in process control. The field evolved from individual loop controls to model predictive control, from linear to nonlinear, and from centralized to distributed control. Further, an extensive overview is presented of all the methods that have been developed to diagnose upsets, and a comparison is made between quantitative, qualitative, and process history–based methods. The new development trend in Supervisory Control and Data Acquisition systems is discussed. The development can be characterized by large-scale computerization as well as a good sense for human factor. The concept of situation awareness is explained. An important issue is alarm management. Alarm flooding forms a potential threat due to operators becoming confused. Several methods have been developed to mitigate and reduce alarm frequency. Finally, attention is paid to the lack of methods to analyze risks at start-up, shut-down, and turn-around stages.
