Delivery

You should create basic LabVIEW Application(s) that Simulate and Control a Level Tank System.

Requirements:

• You can use the built-in PID controller in LabVIEW. The main focus is to create a basic control system to see how it works in a fundamental way, i.e., to use a controller to make the process stay on a given setpoint/reference. NO details nor any knowledge of control theory or deep understanding of PID is necessary to solve this assignment!
• You may explore and use different mathematical models of the Level Tank System. You may also implement the model(s) in different ways: (1) Block Diagram Implementation and (2) using Discretization.
• Make sure to create a proper GUI (Graphical User Interface). It should be possible to change the Model Parameters from the Front Panel, it should be possible to change the PID Parameters and the Reference value from the Front Panel, you should see the process input (control signal, u) and process output (level, h) in one ore more plots. You should also show a graphical representation of the Level Tank where you see the Level goes up and down.
• Find proper PI(D) Parameters by using “Trial and Error”, i.e., run the simulations with different values for the parameters and observe if the results are good or not.
• Make sure you Control Systems works fine when (1) changing the reference value and (2) when changing the outflow (can be defined as a disturbance)
• The code should be well structured and intuitive, e.g., use SubVIs, Labels, etc.
• It should contain basic LabVIEW features like While Loop, Case Structure, SubVIs, Arrays, Property Nodes and Clusters, etc.
• You should use the Project Explorer and make an .exe application
• Make sure to plan your work before you start coding. YOU decide and define the detailed requirements and limitations and set proper assumptions of the system you create. There exists no correct solution that you can put 2 lines below.

Submission: Document your LabVIEW Application (both GUI and code) and deliver a PDF (e.g, 5-8 pages). Here you find a Word Report Template you can use for your report. You can use another template if you prefer. Make sure you fulfill all items in this Checklist before you deliver your Report.

Please follow the "LabVIEW Programming Guidelines" as shown and explained in this video: LabVIEW Programming Guidelines.

Where should you deliver? Canvas

What should you deliver? Only PDF File - No LabVIEW Code

The text should primarily be reflective and not descriptive. The text should not merely describe what has been done, but also why and how and what the results are. The outcome needs to be put into relevant context.

The document (pdf) can be built up as follows (the so-called IMRaD model):

1. Introduction: This documentation can start with a brief introduction, i.e. describe what you have made, what is the purpose with the program, etc. Typically, you should also include a System Sketch. A System sketch is an illustration/figure of your system, the different parts the system consists of, and how they relate to each other.
2. Methods and Results (Overview of the Work that has been done and the Results): Include one or more images of the User Interface (Front Panel) and Code (Block Diagram). These should also be briefly described in the text.
3. Discussions and Conclusion/Summary: Discuss your Results. Finally, a brief summary/conclusion of your work. Does you program work as expected? Why/Why Not, any improvements that needs to be made with your program, etc.

Write Technical Reports in Microsoft Word - Here you learn the basic structure of a Technical Report, how to insert Figure Captions and refer to those in the text, how to insert Equations and refer to those in the text, how to add References, etc.

More information about IMRaD.

Make sure to insert Figures, Tables and Equations correctly, please see the video Equations in Word and PowerPoint.

Referencing: If you have used external sources, you need to use referencing. In scientific documents we typically use the IEEE standard, see Kildekompasset for details. Citation and Referencing with Microsoft Word (YouTube)

Remember to have focus on the technical work that has been done (as you have learned that technical/ professional documentation should be written), i.e., you should NOT tell how much you have learned, that the assignment was interesting and such things. Pretend that you write this documentation for a Customer that have asked you to make this program and document the Methods used and the Results achieved.
