Module description
This module provides a fundamental understanding of the basic concepts of mathematical modeling and control engineering. It starts by providing the necessary mathematical foundation; including Laplace transform techniques and theorems, for modeling and analysing the dynamics of engineering systems. Modeling of engineering systems including mechanical, electrical and electro-mechanical systems then follows using differential equations and transfer function analysis. The fundamental concept of feedback and its impact on system dynamics and control is then analysed in detail, making use of a case study involving speed control of a DC motor. The Routh Hurwitz stability criterion is then studied and used in the design of stable engineering systems. Finally, the fundamentals of proportional-integral-derivative (PID) control are introduced and used in the analysis and design of control engineering systems. The lectures are supported by computer laboratories for modeling and simulation of systems using the Control Engineering toolbox in Matlab.
Module aims
To introduce students to the basic concepts of dynamics and supporting computational techniques. To introduce students to the concepts of feedback and stability. To expose students to standard control concepts and calculations by a detailed analysis of proportional, integral and derivative controls for first and second order systems models.
This module covers Specific Learning Outcomes in Engineering, which apply to accredited programmes at Bachelors/MEng/Masters level. These contribute to the educational requirements for CEng registration (as defined under the UK Standard for Professional Engineering Competence – UK-SPEC).
This module correlates to references U1, U2, U3, E1, E2, E3, E4, D5, D6, P1 and P8. These references are indices of the specific learning outcomes expected of Bachelors/MEng/Masters candidates set out in UK-SPEC, codified with reference to systems used by professional accrediting institutions. A full list of the standards can be found on the Engineering Council's website, at http://www.engc.org.uk

Re-assessment notes
If a module is normally assessed entirely by coursework, all referred/deferred assessments will normally be by assignment.
If a module is normally assessed by examination or examination plus coursework, referred and deferred assessment will normally be by examination. For referrals, only the examination will count, a mark of 40% being awarded if the examination is passed. For deferrals, candidates will be awarded the higher of the deferred examination mark or the deferred examination mark combined with the original coursework mark.
