This unit covers the nature and behaviour of simple components, processes and subsystems relevant to engineering control. Mechanical, electrical, fluid pressure devices and complete elementary control systems are included. Orientation is to predicting, examining and assessing system performance via formation of mathematical models and solution of models. Laboratory experiments and hands-on instruction in the digital simulation package Matlab to solve models. A unified approach to mathematical modelling via the concepts of resistance, capacitance and inertia/inductance is emphasised. Students learn to perform system modelling, develop solution, assess a system response and analyse systems.


At the successful completion of this unit you will be able to:

  1. Identify the significance and relevance of systems and associated control in engineering.
  2. Develop mathematical formulations for linear models (and linearised non-linear systems) through classical and state space modelling techniques for Single Input Single Output (SISO) and Multiple Input Multiple Output (MIMO) systems.
  3. Apply analytical techniques to evaluate system's response, dynamic analysis and stability criteria.
  4. Apply experimental and computer-based control techniques.
  5. Apply S-plane and Routh-Hurwitz techniques to determine the stability of a system.
  6. Appraise dynamic performance of systems in the time and frequency domains using the Bode plot, Root-locus and analyse through pictorial representations such as block diagrams, signal flow graphs, and plots.


Continuous assessment 40%

Examination (2 hours): 60%

Students are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.

Workload requirements

3 hour lectures, 3 hours practice sessions or laboratories (this may alternate with 2 hours lectures and 4 hours practice sessions/laboratories depending on the week) and 6 hours of private study per week
