DESCRIPTION - summary of the module content

The advancement of technology during the 20th century put control engineering on the map - and it plays a critical role in everything from simple household washing machines to high performance F16 aircraft.

This module will give you a fundamental understanding of the basic concepts of mathematical modelling and control engineering. It starts by providing the necessary mathematical foundation; including Laplace transform techniques and theorems, for modelling and analysing the dynamics of engineering systems. You will learn about the modelling of engineering systems, including mechanical, electrical and electro-mechanical systems, using differential equations and transfer function analysis. Furthermore, you will analyse the fundamental concept of feedback and its impact on system dynamics and control in detail, making use of a case study involving speed control of a DC motor. Moreover, you will study the Routh Hurwitz stability criterion, and use it in the design of stable engineering systems. Finally, the module introduces you to the fundamentals of proportional-integral-derivative (PID) control, which you will then use to analyse and design control engineering systems.  The lectures are supported by computer laboratories for modeling and simulation of systems using the Control Engineering toolbox in Matlab.

AIMS - intentions of the module

This module introduces you to the basic concepts of dynamics and supporting computational techniques. It also teaches you the concepts of feedback and stability. Finally, it exposes you to standard control concepts and calculations by a detailed analysis of proportional, integral and derivative controls for first and second order systems models.

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.
