COURSE HANDOUTB. Tech (Chemical Engineering) 5th SemesterCourse Title: Process Dynamics & Control LabDated: 23-06-2014Course Code : CHEM3218Academic Year: 2014-15Course Structure: 0-0-3-21. Instructors: Prof. M.K. Prasad, Mr. P. S. Sagar Course descriptionIn this course, provides introduction to dynamic behavior and automatic control of industrial processes; lab includes open loop, closed loop, and control of process variables by using conventional hardware and real-time digital computers. Experiments are planed; Students will collect and analyze the experimental data using the theoretical principles of process control. Additionally, students will learn to conduct a laboratory experiment safely and will have the opportunity to improve their communication skills through preparation of laboratory reports.

Course Objectives:1. To understand the dynamic behavior of the systems 2. To evaluate response of fist and higher order characteristics.3. Study the installed characteristics of the valve. 4. Study if there is a hysteresis in the control valve and sensor. 5. Evaluate the tuning of a PID control via manual and automatic tuning. 6. Evaluate the effect controller on the control systemCourse Outcomes:At the end of the course, the students will be able to:1. Compare mathematical models response with the physical systems 2. Calculate model parameters which explain the dynamic behaviors of the Process and Control systems 3. Test the range of process variables where the process in stable and controllable.4. Utilize/select available control valves to meet process needs. 5. Choose PID modes that give robust control systems.6. Make use of MIMO Control systems
