Understanding Process Dynamics and Control
Process dynamics refers to the study of how processes change over time in response to various inputs or disturbances. Control, on the other hand, involves the methods and techniques used to manipulate these processes to achieve desired outputs while maintaining stability and operating within specified constraints. Together, these fields are critical for designing and optimizing chemical processes, ensuring safety, and increasing efficiency.
