Unit description*
This unit is aimed at providing electrical engineering students with an understanding of the design
process as it applies to both Power and Control applications. The subject will be divided into two
components; the first looks at the design and manufacture of a power transformer and its use in an
industrial environment. The second is an automatic control application and considers the design of
a position controller, using a PID control loop. Students will analyse a model controller and optimise
the P, I and D settings to satisfy the system specifications.
Intended learning outcomes*
On completion of this unit, you should be able to:
1. Understand the design process and have some concept of the choices that the designer is
faced with.
2. The ability to write a technical report on a project, conveying its important aspects to someone
who has not been involved, but who needs to understand the work, its purpose and findings
3. Be familiar with the concept of a One Line Diagram and its use in an industrial plant.
4. Understand the concept of device ratings, how they are determined and the consequences of
exceeding them.
Generic graduate attributes^
The University has defined a set of generic graduate attributes (GGAs) that can be expected of all
graduates (see http://www.utas.edu.au/governance-legal/policy/documents/alphabeticalpolicy/g/genericattributes_grads1.pdf).
Students will develop abilities in:
The ability to apply knowledge of science and engineering fundamentals
Ability to undertake problem identification, formulation and solution
Work in a team environment with other students
Independent learning and problem solving skills
Understanding the social, cultural, global and environmental responsibilities of the
professional engineer and the need for sustainable development

Expectations
The University is committed to high standards of professional conduct in all activities, and holds its
commitment and responsibilities to its students as being of paramount importance. Likewise, it
holds expectations about the responsibilities students have as they pursue their studies within the
special environment the University offers.
The University’s Code of Conduct for Teaching and Learning states:
Students are expected to participate actively and positively in the
teaching/learning environment. They must attend classes when and as
required, strive to maintain steady progress within the subject or unit framework,
comply with workload expectations, and submit required work on time.
Teaching and learning strategies
Classes will be a mixture of lectures and tutorials, moving from one to the other seamlessly.
Students will be expected to participate in class activities, to answer questions and perform

Occupational health and safety (OH&S)
The University is committed to providing a safe and secure teaching and learning environment. In
addition to specific requirements of this unit you should refer to the University’s policy at:
http://www.admin.utas.edu.au/hr/ohs/pol_proc/ohs.pdf
As standard practice, you must wear clothes appropriate for laboratory work. You
will be asked to leave the laboratory if you turn up wearing thongs, shorts, or a T-shirt !! As per
your workshop practices sessions, you must wear proper shoes, jeans or trousers, and long-sleeve
shirts to protect against spillage or abrasion, and avoid wearing ties or scarves that can get caught
in machinery. Any loose clothing or long hair should be suitably restrained.
The School of Engineering issues a document to all students outlining its OH&S policy for the
School’s Laboratories and Workshops. It is a requirement that all students must have read this
document prior to entering any of the School’s workshops or laboratories.
“Students and staff working in the Civil & Mechanical Engineering laboratories are required to
conform to the following dress requirements:
Protective footwear conforming with AS2210 having protective toe caps, full length trousers, tight
fitting protective long sleeve jacket or coat, no loose clothing or hair. “
Specific attendance/performance requirements*
The Faculty of Science, Engineering and Technology states that all students must attend
a minimum of 2/3rds of all lectures and tutorials. This policy may be viewed at
http://fcms.its.utas.edu.au/files/policies/Faculty%20Assessment%20Guidelines%20Nov%

Review of results and appeals
It is expected that students will adhere to the following policy for review of any piece of continuous
assessment.
1. Within 5 days of the release of the assessment result, the student should request
an appointment with the Lecturer. The student should be prepared to discuss
specifically which section of the marking criteria they are disputing and why they
consider the mark is inappropriate.
2. Following this discussion, students may request a formal remark of the original
submission (in accordance with Rule of Academic Assessment 111, clause 22.1).
This remark will be undertaken, where practicable, by an alternative assessor.
3.
Students may also request a review of the final result in a unit. The request and payment must be
made within 10 days from the date of the result notification. Students are referred to Rule of
Academic Assessment 111, clause 23 at http://www.utas.edu.au/university-council/universitygovernance/rules and
http://www.studentcentre.utas.edu.au/examinations_and_results/results/result_review_results.htm
.

Academic referencing*
In your written work you will need to support your ideas by referring to scholarly literature, works of
art and/or inventions. It is important that you understand how to correctly refer to the work of others
and maintain academic integrity.
Failure to appropriately acknowledge the ideas of others constitutes academic dishonesty
(plagiarism), a matter considered by the University of Tasmania as a serious offence.
For information on presentation of assignments, including referencing styles:
http://utas.libguides.com/referencing
Please read the following statement on plagiarism. Should you require clarification please see your
unit coordinator or lecturer.
Academic misconduct*
Academic misconduct includes cheating, plagiarism, allowing another student to copy work for an
assignment or an examination and any other conduct by which a student:
(a) seeks to gain, for themselves or for any other person, any academic advantage
or advancement to which they or that other person are not entitled; or
(b) improperly disadvantages any other student.
Students engaging in any form of academic misconduct may be dealt with under the Ordinance of
Student Discipline, and this can include imposition of penalties that range from a
deduction/cancellation of marks to exclusion from a unit or the University. Details of penalties that
can be imposed are available in Ordinance 9: Student Discipline – Part 3 Academic Misconduct,
see http://www.utas.edu.au/__data/assets/pdf_file/0006/23991/ord91.pdf.
Plagiarism
Plagiarism is a form of cheating. It is taking and using someone else's thoughts, writings or
inventions and representing them as your own; for example, using an author's words without
putting them in quotation marks and citing the source, using an author's ideas without proper
acknowledgment and citation, copying another student's work. If you have any doubts about how to
refer to the work of others in your assignments, please consult your lecturer or tutor for relevant
referencing guidelines, and the academic integrity resources on the web at:
http://www.academicintegrity.utas.edu.au/
The intentional copying of someone else’s work as one’s own is a serious offence punishable by
penalties that may range from a fine or deduction/cancellation of marks and, in the most serious of
cases, to exclusion from a unit, a course or the University.
The University and any persons authorised by the University may submit your
assessable works to a plagiarism checking service, to obtain a report on possible
instances of plagiarism. Assessable works may also be included in a reference
database. It is a condition of this arrangement that the original author’s permission is
required before a work within the database can be viewed.
For further information on this statement and general referencing guidelines, see
http://www.utas.edu.au/plagiarism/ or follow the link under ‘Policy, Procedures and Feedback’ on
the Current Students homepage.
