Most industries operational today aim to automate their processes to the greatest extent. Automatic process control, if programmed and maintained carefully, eliminates the human errors that have led to tragic plant-wide accidents in the past. This introductory course covers basics of process control. The course begins with the introductory concepts, followed by the mathematical modelling. This knowledge base will be beneficial to understand the dynamic behaviour of chemical processes. A major focus will be on the design of feedback controllers, including their tuning and stability analysis. Later, discussions on several advanced control systems will introduce the class to actual systems employed in industries. The course ends with exposing the class with designing practical plant-wide control systems.
