Teaching Rationale And Relationship
Lectures provide the core materials as well as guidance for further reading. Tutorials offer the opportunity for practice in the analysis of a system's models and a system's behaviour. Some aspects of the course are further re-enforced through laboratory experiments.
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
There are four assessment methods for this module;
A 1.5 hour examination, assessing the students' knowledge of the core material in a traditional written examination.
A 3 hour open book assessment carried out with access to any printed material and use of Matlab/Simulink simulation software. This is to assess the students' ability to apply the course material to a more practical situation, in simulating and obtaining results from various control scenarios.
A 1 hour mid-term test gives the student the opportunity to assess their understanding of the course at an intermediate point, with only 5% of the module at risk, and take appropriate action in time for the remaining 80% of examined marks.
Two laboratory reports are to be written, one covering the electrical machine experiments and the other covering the control systems experiments.
Semester 1 Study Abroad students will be able to sit the assessment earlier.
