NPTEL Courses

Process Control and Instrumentation

Automatic Process Control is being used in almost all the industry verticals today. This introductory course covers basics of process control and the instrumentation used for it. The process control part begins with the introductory concepts, and mathematical modeling and its use for control purposes. Subsequently, the dynamic behavior of chemical processes will be discussed. This course goes deeper into the design of feedback controllers. A special emphasis will be placed on the controller tuning and stability analysis. Several advanced control systems will also be covered under the process control part. The instrumentation part will elaborate the valve characteristics along with the working principle, specifications, design and selection aspects of various measuring sensors. (from nptel.ac.in )
