|Brief Handbook Description:||This unit aims to teach the basic issues involved in the analysis and design of computer-controlled systems. The emphasis is on theory rather than technological application or industrial practice.
However, students are expected to test some of these ideas on a few benchmark control problems in the laboratory. Completion of the unit will facilitate progression to advanced study in the area and to work in industrial control. This unit assumes a basic knowledge of calculus, functions of real variables, Laplace transform, matrix theory and control theory.
The following topics are covered. Sampled data systems: aliasing. Zero order hold equivalent: inverse of sampling, sampling system with time delay. Properties of difference equations: solution, stability, change of co-ordinates, Z transform. Input output models: pulse response, pulse transfer operator, pulse transfer function, interpretation of poles and zeros.
Analysis of discrete time system: stability (Jury's test, Nyquist criterion, Lyapunov method), sensitivity and robustness, observability (observers, reduced order observers), reachability and controllers, loss of reachability/observability through sampling, output feedback, the Separation theorem. Optimal control: Kalman filter, linear quadratic regulator, output feedback, the Separation theorem.
Approximating continuous time controllers. Finite word length mplementations.

|T&L Activities:||Tutorial: Problem solving sessions. They also use computing facilities at times.
Independent Study: Students need to do some preparation for tutorials. They may also need to read the text and other references to fully master the basic concepts covered in the lectures.
Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.
|Attribute Development Method||Attribute Developed|
|Proficiency in creatively applying technical principles, design methodology, and knowledge of tools and materials in the design of computer control systems.||Design (Level 4)|
|Develop in-depth technical skills and knowledge of computer control systems.||Engineering/IT Specialisation (Level 4)|
|Mathematical modelling and simulation of dynamic systems and controllers.||Maths/Science Methods and Tools (Level 4)|
|Knowledge in how to produce clear and well-constructed engineering documents and informative diagrams and models for computer control systems.||Communication (Level 2)|
|Develop an understanding of the theory behind computer controlled systems and the technological applications of computer-controlled system in parcatice.||Professional Conduct (Level 2)|
For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table.
Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.Design (Level 4)
Tutorials: There will be 11 tutorials (of duration 2 hours each) during the semester. Tutorials will include analytical problem solving sessions on the material covered in the lectures and computer aided solution / illustration. These sessions will give you the opportunity to explore the concepts in detail and are very helpful in understanding the material covered in the lecture. They will also require you to model and simulate dynamic systems and controllers in Matlab. Tutorials 2-11 are worth 2 marks each and you will be awarded a mark of 0, 1, or 2 based on your participation and completed work during the tutorial. Besides this incentive, in my experience I have found that there is a direct correlation between the tutorial participation and the exam performance of the students. The solutions for the tutorials and computer codes will be available from the unit of study web page after the session.
Midterm Exam: The midterm exam is scheduled to provide you an assessment halfway through the semester and more importantly to give you a practice run for the final exam. It will be of the same format as the final exam (but of shorter duration). Again the solutions will be available on the unit of study web page after the exam. Both the midterm exam and the final exam will be based on the lecture material and tutorials. Both exams will be closed book and closed notes. They will test your conceptual understanding of the material. Any complex formulae needed, will be provided on the question paper.
Final Exam: Final Exam
|Assessment Feedback:||Marked Mid-Sem Exam will be returned to the students. There is detailed discussion during tutorials.|
|Policies & Procedures:||See the policies page of the faculty website at http://sydney.edu.au/engineering/student-policies/ for information regarding university policies and local provisions and procedures within the Faculty of Engineering and Information Technologies.|
Note: Students are expected to have a personal copy of all books listed.
