The aim of the course is to provide students with a basic understanding and concepts of control systems. The course starts by introducing basic concepts of feedback control systems using a number of practical examples. Mathematical modelling of physical systems and representing them in block diagrams with transfer functions are presented. Basic control system response characteristics (stability, transient response, steady state response) and analysis and design procedures are introduced using first and second order systems. Analysis of control systems using Routh-Hurwitz criterion, root locus, and Bode plot methods are considered.
|Session||First Sub Session||Credit Points||15 credits (7.5 ECTS credits)|
1. Basic System Concepts: Open loop systems; closed loop systems; feedback; disturbances; sensitivity.
2. Models: Differential equations; characteristics of linear system; significant non-linearities; transfer functions; block diagrams and block diagram algebra;
modelling of electromechanical and electrohydraulic components and systems; characteristic equation.
3. Time domain performance analysis: test inputs; transient and steady state response; response parameters; poles; stability; Routh-Hurwitz; low order
systems and approximations.
4. Root locus analysis & design: Control system performance analysis using root locus method. Control system design using root locus method: PID controllers
and lead-lag compensators.
5. Frequency domain analysis & design: Graphical presentation, Bode diagrams; frequency domain stability criterion; gain and phase margins. Frequency
domain compensation using Bode diagrams, lead and lag compensators.
Available only to students following an Honours degree programme.

Information on contact teaching time is available from the course guide.
1st Attempt: One written examination of three hours duration (80%) and continuous assessment (20%) based on:
Tutorial Participation/class test (10%)
Laboratory/design exercises (10%).
Resit: One written examination of three hours duration (80%), with previous coursework marks used to make up the remaining (20%).
Three practical sessions will be undertaken by the students. Assessment will be based on submission of formal reports.
a) Students can receive feedback on their progress with the Course on request at the weekly tutorial/feedback sessions.
b) There will be tutorial sessions dedicated to feedback on sample exam paper questions at various times through the course.
c) Students requesting feedback on their exam performance should make an appointment with the course coordinator within 2 weeks of the publication of the exam results.
