Overview

The ability to analyse and control the dynamic behaviour of machinery and processes is core competency for mechanical engineers. In this unit, you will be introduced to the theory and techniques that underpin dynamic systems analysis and control system engineering, including: transfer function representations, stability, steady-state behaviour, and frequency response. You will then use these techniques to design controllers to achieve certain transient and steady-state performance criteria. Together, these concepts and analysis tools will provide you with a solid foundation to develop real-world controllers, including the ubiquitous proportional-integral-derivative (PID) controller. In this capstone unit, you will draw on the earlier dynamics units EGB321 Dynamics of Machines, and EGB211 Dynamics. An embedded mathematics module, constituting 20% of the unit, provides advanced methods that support student learning in the engineering context.

Learning Outcomes

On successful completion of this unit you will be able to:

  1. Apply the fundamental principles of dynamics to machine vibration and controlanalysis, at a mastered level.

Learning Approaches

In this unit you can expect to experience the following timetabled activities:

  • Formal lectures from experienced engineers and mathematicians that will activate your understanding of theories and principles, and model approaches to solving problems. You will have the opportunity to ask questions during these lectures.
  • Workshop classes that will give you the opportunity to work collaboratively with your peers to solve problems. These will be facilitated by teaching staff and will provide an opportunity to test your understanding and gain feedback on your work. You will also work collaboratively to conduct simulations to give you experience with dynamic systems and controller design.
  • There will be 4 weeks of mathematics lectures in weeks 1-4. The mathematics lectures will each be 2 hours and supported by exercises in the workshops, which will be facilitated by instructors to provide guidance and feedback on your learning.
  • To complement timetabled activities, you can expect to be provided with learning resources including videos and readings on a unit Canvas site that you can access flexibly to complete your learning in this unit. Success in this unit will require you to manage your time to ensure you have focused time each week (beyond timetabled activities).

At the beginning of the unit, you will be made aware of the ways in which you can ask questions or seek clarification from the Unit Coordinator and Tutors.

You are expected to:

  • Engage with timetabled activities on campus and ask questions.
  • Manage your time to engage with online resources outside of timetabled activities. These will be available on the unit Canvas site. You will receive regular email announcements regarding release of these resources.
  • Engage with your peers in a learning community to practise problem solving and then work independently to complete your assessment tasks.
  • Prepare for timetabled classes and activities and follow up on any work not completed.
  • Complete assessment tasks by working consistently across the semester and meeting the due dates that are published via the unit Canvas site.

Feedback on Learning and Assessment

You will have the opportunity to practice and reflect on what you are learning with a range of unmarked exercises throughout the semester, including skill assessments assigned as formative homework. Feedback will be provided from both teaching staff and peers during the workshops and computer labs.

Assessments will be marked against criteria and standards which will be shared with you via rubrics and discussions with your lecturers/tutors on your draft assessments. Marked assessments will include feedback from the markers against the rubrics.

Assessment

Overview

As you progress through this unit, you will develop both a theoretical understanding of dynamic systems and learn to deploy practical analysis and design techniques that are important for professional engineering practice. The assessment for the unit is designed to test your learning against the unit learning outcomes, and includes problem solving tasks (50%) where you will report on the modelling,analysis, and simulation of dynamic systems and the design of controllers using both hand calculations and computer tools (e.g. MATLAB). A comprehensive written examination (50%) will assess both your theoretical understanding and your ability to deploy the analytical techniques you have developed in the unit. The mathematics assessment constitutes 20% of the total assessment in this unit

Academic Integrity

Students are expected to engage in learning and assessment at QUT with honesty, transparency and fairness. Maintaining academic integrity means upholding these principles and demonstrating valuable professional capabilities based on ethical foundations.

Failure to maintain academic integrity can take many forms. It includes cheating in examinations, plagiarism, self-plagiarism, collusion, and submitting an assessment item completed by another person (e.g. contract cheating). It can also include providing your assessment to another entity, such as to a person or website.

You are encouraged to make use of QUT’s learning support services, resources and tools to assure the academic integrity of your assessment. This includes the use of text matching software that may be available to assist with self-assessing your academic integrity as part of the assessment submission process.

Further details of QUT’s approach to academic integrity are outlined in the Academic integrity policy and the Student Code of Conduct. Breaching QUT’s Academic integrity policy is regarded as student misconduct and can lead to the imposition of penalties ranging from a grade reduction to exclusion from QUT.
