Contact hours: The course consists of 3 hours of lectures per week, 1 hour of tutorial every two weeks, and 3 hours of laboratory every two weeks. Check the website http://www.timetable.unsw.edu.au/current/elec3114.html for updated schedule. It is not reproduced here, as the website is the definitive source of information, and schedules may change. Lectures start in Week 1. Laboratory starts in Week 2. Tutorials start in Week 2. Consultation sessions start in Week 3. Course details Context and aims The overall course aim is for you to gain true competence in basic control, and to learn how to: examine a physical process and identify its main features in terms of signals and blocks, assess whether it may be difficult or easy to control the process, ELEC3114 p. 1/6
specify a reasonable control performance, design a simple controller to achieve that performance, and design and use simple controllers for laboratory processes. The fundamentals which will enable you to do this are feedback, the responses of linear systems to standard inputs, analysis of the stability of linear systems, and the design of linear feedback systems capable of attaining specified performance criteria.

Teaching strategies More important are learning strategies that you have to adopt. Learning is effortful - you have to make the effort. You have to develop your own mental models for how things work. I can give you insights, but you have to develop your own schema. You learn from errors and from discovering misconceptions. You cannot do this just by listening or reading. You have to try things out. Firstly, close your books and explain and write down concepts for yourself or for friends. Check. If your concept is not complete and accurate, do it again. You learn through the tip of your pen. Do all the tutorial problems to test your new-found understanding. You learn by doing. Make sure you become competent in the laboratory. Laboratory sessions are unstructured for precisely this reason. You will not be given a list of things to do and check off. The ultimate test of whether you have learned something is whether you can use it next year, or when you begin working. Only your schema are enduring. You will forget details, and setting out to simply memorise things is worthless - of minor assistance for exams only. Lectures The lecture times will largely be used to explain the underlying theory and discuss examples. The lectures will cover the same topics as in the prescribed textbook, so lecture notes will not be distributed. It is your responsibility to make your own notes. You are expected to attend the lectures and prepare yourself for them. Tutorials You are expected to attempt to solve given tutorial questions before attending the tutorial and to attend the tutorials. Laboratories The laboratory sessions will focus on your learning about the equipment and what the control issues really are. You will be expected to be competent in the lab by the end of the course. Most laboratory sessions will be flexible in that you may work in groups (maximum 2 students per group) or individually, helping each other and consulting the demonstrators to the extent you need. However, you will be tested individually on what you have learned in the laboratory sessions. Every student must have a laboratory book. The science pads on sale in the campus shops are satisfactory. You must record everything you do and try, right or wrong. Please follow the lab rules and pay attention to instructions from your lab demonstrators, they are there to assist you. The demonstrators will enforce the lab rules. Attendance of the labs will ELEC3114 p. 3/6
be taken and your attendance will only be accepted if you are not late by more than 15 minutes, any later than that the lab demonstrator will not take your attendance. Please only attend the lab session that you signed up for, do not move to a different session without prior consent from me. If you may miss a lab due to valid reasons (illness, family emergency, etc) you need to get in touch with me before the lab with suitable supporting evidence (e.g., a medical certificate) and schedule a make up lab. Consultation hours You can come to see me in my office if you need to discuss anything regarding the course materials on (i) Mondays, Weeks 3-13, 4 5 pm, and (ii) Fridays, Weeks 3-13, 4 5 pm. Assessment The following are the assessment components for this course: Assessment component Information Lab attendance Attendance counted only if not more than 15 minutes late. Must attend 4 out of 5 labs to pass the course. Quiz 1 In Week 6. Worth 5% of total marks and marked out of 5. Will be run online on Moodle after hours. More details will be provided in Week 3. Midsession exam In Week 8. Will cover materials from Week 1 to Week 6. Worth 20% of total marks and will be scored out of 20. Midsession will be conducted after hours on the Thursday of Week 8 (to be confirmed) within the time window 6 pm 9pm. Length of exam will not be 3 hours but anywhere between 1 and 2 hours. Quiz 2 In Week 10. Worth 5% of total marks and marked out of 5. Will be run online on Moodle after hours. More details will be provided in Week 3. Lab exam Weeks 11 and 12, during your regular lab session time. Worth 15% of total marks and marked out of 15. Must pass this exam (score at least 7.5 out of 15) to pass the course. Further details will be provided in Week 9. Final exam Worth 55% of total marks. Marked out of 55. Note: All students are required to do the labs unless they submit a lab exemption request supported by exceptional circumstances. Such requests must be submitted by the end of Week 2. Until an exemption is granted you will have to attend the labs. If granted then the final exam weightage will be increased by the lab test weightage (15%). If you have a valid reason (with supporting evidence) not to attend a quiz, submitted beforehand, then the final exam weightage will be increased by the quiz weightage (5%). If you will be unable to attend the midsession exam you must submit a Special Consideration request. If Special Consideration is granted then the final exam weightage will be increased by the midsession exam weightage (20%).

book website MATLAB library resources http://www.wiley.com/college/nise http://www.mathworks.com http://info.library.unsw.edu.au/web/ services/teaching.html Computer resources MATLAB MATLAB has become an industry standard, and an essential tool for the modern engineer. It is assumed that you are familiar with the basics of MATLAB. Various aspects of MATLAB use and programming will be required in laboratories, but are also useful for problem solving and any project work. Further, familiarity with MATLAB can be a great help in learning control as it allows one to quickly set up examples and test ideas. A useful website on control tutorials for MATLAB is: http://www.engin.umich.edu/group/ctm/ A CD containing Matlab may be borrowed overnight (against a student card) from room EE G15A. For those students who do not have their own computers, access to these two programs is available in the undergraduate computer laboratory (EE G16).
