Assessment

The performance of the students in this laboratory is assessed through four modes:

Preparation, Participation and Logbook (5%)

    The laboratory consists of 5 milestones:

    1. Introduction to Simulink and the Hilink hardware;
    2. Modelling and linearity investigation;
    3. Open-loop frequency response;
    4. Proportional control of a DC motor;
    5. Proportional and integral control of a DC motor;

At the start of each laboratory session every student will be expected to have a undertaken preparation for the lab. This consists of lab preparation questions and a written summary of what they are planning to do in that laboratory session on the laboratory logbook. The preparation will be checked and marked randomly during the lab session.  If they do not have such a document, they will be asked to leave the laboratory and prepare it. The summary should contain all the information asked for in the Preparation for the milestone they are about to do.

  • Answers to the questions asked in the preparation section of the experiment (exp4&5)
  • There should be block diagrams with transfer functions for the systems.
  • Circuit connections should be given in a diagram.
  • Bode plots or root locus should be presented with the design constructions.
  • Tables should be prepared for results with values chosen where measurements will be taken.
  • Graphs prepared with axes labelled with scales and names where data are to be plotted.

Not all groups will be able to complete each milestone in one laboratory session. Each group should be planning to complete all the 5 milestones by the end of the session. There is a catching up lab at the end of the session that you can use to complete your work. 

Each student should have a laboratory logbook with hardcover, a pile of paper is not acceptable.  The laboratory logbook dates and records his/her activities for this laboratory including the preparation, diagrams of the system, the measurements taken, the analysis, design and comment on the experiments.  Each student should ask the lab supervisor/demonstrator to sign the book before leaving the laboratory.  Otherwise, no mark will be given. 

On the completion of a milestone, each student is expected to produce a preliminary report in the laboratory notebook for the work carried out.

  • Plots will have to be presented in printed version. Hand made plots are not acceptable, as they are not accurate enough.
  • Measurements will be shown in tables, and will have to be accompanied with all the programs and parameters necessary to reproduce the experiment.
  • A few lines of the conclusions that were drawn from the experiment.

 It needs to be separate from the lab report.

 

The first Laboratory report (5%)

You should write and submit a report for the preparation of Experiment 4.  This report will be marked making a contribution to your final mark.  During the experiment you may be asked to answer questions or demonstrate skills for the experiment for marking.   You should be able to demonstrate that you are capable of doing this experiment by self-learning.

 

This report must be submitted to the demonstrator at the beginning of your week 8 laboratory if you are in an even week laboratory (at the beginning of your week 9 laboratory if you are in an odd week laboratory).  You are not allowed to do the experiment before submitting the report. 

 

The report should answer each questions as concise as possible.  Tables and graphs should be used as much as possible.   The report should be written in such a way that another person in the same laboratory can understand and reproduce your results in minimum time.  Make sure you include all the programs.

The Second Laboratory Report (10%):

At the end of the session, each student will submit a final report which should be well structured according to the milestones and steps defined in each milestone.

The due date for the lab report & lab logbook will be 11:30 am, Friday of week 13 of the session. You need two separate coversheets and the items must be submitted separately.

The report will be marked out of 10. The report should include mainly the work carried out by the student without any theory. It should be written in an interesting and informative manner. You should aim to provide the reader (marker) with as much information about your activities in the laboratory as you can with a minimum of superfluous words. However the report must be written in well constructed English sentences and not just be a set of tables, graphs and dot points. Try and construct your story about how the system was designed and how it behaved compared to its expected behaviour. Also you should comment on any difficulties you encountered and how accurate you think your values are. Graphs and pictures of results should appear first with tables of results in an appendix.

The report should consist of:

    1. All the measurements carried out in the laboratory in an organized manner.
    2. All the diagrams requested to be produced in the report.
    3. The details of the design procedures carried out in the project.

An example of how your lab report should look like can be seen by clicking this link.

Optional Component:  This optional component aims to provide you with an opportunity for a more challenging experiment of real time control of a DC motor.  No extra mark will be given for this part. Please note that no assistance will be given to help you undertake the optional component.

Because it is an optional component you will lose no mark if you choose not to do it.
