Module overview

Control in its application spans across all areas of Engineering and far beyond. This module provides fundamentals of linear, time-invariant control system analysis and design in time domain, as well as practical aspects of applying control in chemical process engineering.

Module aims

A systematic understanding and critical awareness of the importance of control in engineering

A knowledge of control system analysis

A knowledge of the techniques used to design linear and time-invariant control systems

An understanding of Laplace transform for solving engineering problems.

Module content


Introduction: terminology, the concept of control, the feedback control mechanism,;

Process modelling: Concept, the transfer function and its characteristics, the system response from the transfer function, the block diagram and system simplification;

Laplace transform: definition, derivation of simple Laplace Transforms; operational properties, inverse Laplace Transform; first shift theorem, unit step functions, second shift theorem; application to solution of systems of linear differential equations. Impulse function, transform of period functions, convolution theorem;

Linear system analysis in the time domain: Response of the first-order, second order and higher order systems,  system response versus pole location, response of the time-delayed systems, system stability;

Design of control systems in time domain: Closed loop vs. open loop systems, general requirements of control systems, automatic controllers (P, PI, PD and PID), tuning of PID controllers;

Practical aspects of process control: Typical sensors and actuators; design of control system for typical processes;

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

Introduce principles of control systems analysis and design through theory and worked examples. This is mainly delivered through lectures and tutorial classes with independently worked out examples.

The learning and teaching methods include:

3 hours lecture per week x 11 weeks
1 hour tutorial x 11 weeks
2 hours revision lectures

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate understanding of scientific principles, methodologies and mathematical methods associated with control systems as well as the ability to analyse and design particular systems in the final examination. The inter-semester test amplifies awareness and ability to devise control concept and to analyse systems from their response.

Thus, the summative assessment for this module consists of:

In-semester test   [Learning outcomes 1, 2, 3]              (1 hr)                     (20%)
Examination            [Learning outcomes 1, 3, 4, 5]     (2 hrs)                     (80%)

Formative assessment and feedback

Formative verbal feedback is given in tutorials
Formative feedback on multiple choice tests are given verbally and available on SurreyLearn to provide feedback on understanding control systems analysis and simple design
