Process Control and Dynamics is a specialized field of control systems engineering that focuses on analyzing, designing, and automating the regulation of industrial processes, such as those found in chemical manufacturing, power generation, and pharmaceuticals. It involves creating mathematical models, often using differential equations, to understand the transient behavior—or dynamics—of key process variables like temperature, pressure, and flow rate in response to disturbances or changes. This dynamic understanding is then used to design and implement control strategies, typically executed by computer-based systems like PLCs or DCSs, which use feedback mechanisms (most commonly PID controllers) to manipulate inputs and maintain the process at a desired, stable, and efficient operating point.
