Process Dynamics And Control

Primarily intended as a textbook for the undergraduate students of chemical engineering, it introduces students to fundamental principles in system dynamics and control. This book bridges the conceptual gap by using a number of examples from physical as well as from different facets of human experience.

The text introduces the concepts of State variable techniques and MIMO systems. An indigenously developed simulation platform for open and closed loop simulation has been introduced for analysis and design of dynamic processes. All the topics in this text are supported by quite a number of worked out and exercise problems.

The Accompanying CD with this book includes a number of computer programs to verify the results obtained during the open and closed loop dynamic studies. It also contains a number of Demonstration Programs exposes concepts of process dynamics and the CD exposes various control through extensive use of animated graphics.

This text guides students to:

Model and simulate the behaviour of first, second and higher order dynamical systems.
Design and tune feedback and feedforward controllers, and obtain a hands-on experience in doing this via simulation.
Configure and analyze control loops for stability and performance.
