      Week 5 
       
      5.1 System modelling and simulation in LabVIEW 
       
      Suppose a DC motor mathematic model can be described by the following inputoutput
      differential equation: 
      where ω(t) is the angular velocity of the motor shaft, u(t) is the input voltage, and a, b 
      are model parameters. 
      In order to find the values of the model parameters a and b, an experiment was carried 
      out by injecting a square wave voltage to the motor (i.e., u = 0-1Vpp). The angular 
      velocity of the motor is not directly measurable, however, the motor has an integral 
      angle sensor to measure the rotational angle of the motor shaft θ(t). 
      During the experiment, the input voltage and the rotational angle signals are collected 
      with a sampling period of 0.1 second, the curves of which are shown in the following 
      figure. 
       
      One dataset in the above figure is tabulated below, which is sufficient to solve the 
      problem in this task.

      Assuming the following relationship 
      1) Use the above data to estimate the values of model parameters a and b. Provide 
      the details on your working step. 
      2) Build the model in LabVIEW (Do NOT use mathscript-node, formula-node or 
      MATLAB-script in this task) and simulate the response of the model to a 0-1Vpp 
      square wave input voltage with period=5 second and duty cycle=50% (refer to the 
      above figure) for 7 seconds. Display the simulated output angle and the square 
      wave input signals in the same graph (results are expected to be similar to the 
      above figure), and then discuss and justify the correctness of your results. 
       
      5.2 Mechatronics Project – Teamwork

      Page 17 of 21 
       
      You may use multiple ‘select’ nodes for ‘case structure’). 
      4) Display at least 2 periods of the trapezoidal wave on a waveform chart. 
      5) Organize components in your front panel and block diagram for readability. 
      6) Provide screenshot of both the front panel and block diagram in the portfolio 
      report. 
       
      6.3 Circuit design 
       
      An analogue control circuit as shown in the following figure is used to implement the 
      controller output u according to the following equation: 
           =      − 0.5     
      where r and      are the input signals to the circuit. 
      Calculate the values of the resistors R1 and R2 such that the circuit can implement the 
      above controller equation. Provide your calculation steps in the portfolio report.

      Week 7 
       
      7.1 LabVIEW – Simulation of a PID control system 
       
      In this task, students are asked to create a control system simulation with a PID 
      controller in the ‘control and simulation loop’. 
       
      The following figure describes a simple mass-spring-damper system to be controlled, 
      where m is the mass of a moving object; u is the external control force; y is the 
      displacement, k is the spring constant; and b is the friction coefficient. 
       
       Based on Newton's second law, the equation of motion of the above system can be 
      described by the following differential equation 
      If the parameters are known as m=1, b=15, and k=25, then we have 
       
      Alternatively, you can equivalently convert the above equation as a transfer function: 
       
      1) Start a new file in the LabVIEW and save it as Week7p1.vi 
      2) Students should use Control & Simulation Loop in Control & Simulation >> 
      Simulation with the configuration shown in the following figure 
       RME40002 Mechatronics Systems Design – Portfolio Tasks Description 
      Page 19 of 21 
       
       3) In the Control & Simulation Loop, students should create a PID controller, 
      plant and reference signal. 
      4) The requirement for the reference is the same as the square wave in Week 6 
      tasks. Students can reuse the program week6p1.vi. 
      5) Students can use PID blocks in Control & Simulation >> Simulation >> 
      Continuous Linear System or PID.vi in Control & Simulation >> PID or build 
      PID from integrator and derivative blocks. 
      6) Plant Model can be created by basic integrator blocks or Transfer function 
      block in Control & Simulation >> Simulation >> Continuous Linear System. 
      7) Tune the PID parameters until the design specifications are satisfied: the 
      steady-state error less than 5%; the settling time less than 0.25 second. (Settling 
      time is the time required for the response curve to reach and stay 5% of the 
      final value). 
      8) Organize components in your front panel and block diagram for readability 
      9) Provide screenshot of both the front panel and block diagram in the portfolio 
      report. 
      10) Discuss how the PID control parameters affect the settling time and steadystate
      error in the portfolio report.

      Week 8 
       
      8.1 LabVIEW – Counter design (Do NOT use Mathscript-node, formula-node or 
      MATLAB-script in this task) 
       
      In this task, students will create a click speed test program by using LabVIEW. 
       
      1) Start a new file in the LabVIEW and save it as Week8p1.vi 
      2) The test lasts for 10 seconds and the time spent is shown in “Elapsed time” 
      3) A user can click a button with the label “Click Me”. 
      4) When a user clicked the button, the “Counter value” is incremented by 1, and 
      the last moment when the button is clicked is recorded in “Last time clicked”. 
      5) Students can use the ‘Count up’ block in Real-Time>>Function blocks. 
      6) The period is defined as the time difference between the last time clicked and 
      the second last time when the button was clicked. 
      7) Finally, the smallest period is shown in the “smallest period”. 
      8) Organize components in your front panel and block diagram for readability 
      9) Provide screenshot of both the front panel and block diagram in the portfolio 
      report. 
      Example: 
       
      8.2 Mechatronics Project – Progress reflection 
      By this week, your group should have made some progress on the project 
      development. Address the technical development your group have completed and 
      point out your main contributions. What are the gaps between your group’s current 
      progress and the initial plan? How to fill the gaps in the remaining weeks? 
      Provide reflection on your learning experience, time management, and teamwork 
      involvement. 
       
      Approximately 200 words are required in this task. 
       
      Second portfolio submission due by this week: 
      You should submit your second portfolio by the end of this week. Refer to the 
      Instructions in Page 2 of this document for details.
