Process Control BTCH-21603

Course Objective : Introduce the fundamentals of process control with applications using P, PI, and PID controllers. The course will teach the students about mathematical models based on transfer function approach for single loop systems, how to obtain dynamic response of open loop and closed loop systems, stability analysis in transient and frequency domains, and controller tuning methods. The course would end with more advanced concepts like feed-forward control, ratio control, model-predictive control, ratio control, dead-time compensation, etc. 
Course Contents:
 1 Introductory Concepts:  Need for control and automation, control logic, servo and regulatory control, block diagrams, control structures (feedback vs. feed forward), process and instrumentation diagrams. 
2.Laplace Transform:  Laplace transforms, solution of ODEs using Laplace transform. 
3.Linear Open Loop Systems :  Transfer function approach, response of first order systems: step, impulse and sinusoidal response, first order systems in series. 
4 Higher Order System: Second order systems, higher order systems, transportation lag and dead time . 
5 .Linear closed loop systems:  Linear closed loop systems, development of block diagrams, classical feedback controllers. Final control element (control valves), block diagram reduction techniques . Closed loop response, servo and regulatory problems.
 6.Stability Analysis :  Stability analysis, Routh stability criterion, Root locus diagrams (rule based). Introduction to frequency response, Bode diagrams, Nyquist plots, Bode and Nyquist stability criterion. 
7.Introduction to advanced controllers: cascade control, feed forward control, ratio control. 
 
Course Outcomes: Students will be able to 1.Understand the importance of process dynamics (unsteady state operation) 2.Students will understand different types of controller. 3.Tune a controller to Stability and disturbances or manage operating point transitions. 4.Student will learn about block diagram and other advanced control system.
