Welcome to "Process Control & Instrument" module:

 

This module aims at imparting the knowledge on the fundamentals of process dynamics, control and instrumentation. It is the ultimate objective of the module that students at the end of the course module should have concepts on control strategies that are adopted and practiced in every process plants and industries.

 

Introduction

 

The course will cover the basics of modelling, the use of Laplace transform in control theory and its application for evaluating transfer functions. The module further covers in detail block diagram, its algebra, feedback and feed forward control methods and blocks diagram reduction. Stability analysis, Root locus method and various instruments used for measuring the process plant parameters will be also covered in this module.
