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, application of Laplace transform for model analysis;

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, enhanced single-loop controllers;

Practical aspects of process control: Typical sensors and actuators; practical considerations in controller design, design of control system for typical processes.

Assessment pattern

Assessment type Unit of assessment Weighting
School-timetabled exam/test IN-SEMESTER TEST (1 HOUR) 20
Examination EXAMINATION (2HRS) 80

Alternative Assessment

A coursework-equivalent to the in-semester test will be offered as an alternative assessment.

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 assessment questions (and sample solutions as feedback) every 3 weeks

  • Formative feedback on in-semester test are given verbally and available on SurreyLearn to provide feedback on understanding control systems analysis and simple design

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
  • A knowledge of practical issues in control system design and analysis

Overall student workload

Independent Study Hours: 106

Lecture Hours: 33

Tutorial Hours: 5

Laboratory Hours: 6

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/computer lab x 11 weeks

  • 2 hours revision lecture

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
