TASKS:
a) This task involves evaluating the following two mathematical models:
i. Transfer function (low fidelity)
ii. Simscape (high fidelity)
Your task is to determine one positive and one negativefor each model. You should populate your answer in Table 2-1.
b) For this task, you should undertake the design of a proportional control gain, K_pfor one of the following:
Angle control of the DC motor
Angular velocity controlof the DC motor
Root locus:
For this you should initially investigate the effect of the proportional control gain, K_p using the Root Locus method within MATLAB. The requirements of the two control systems are given in Table 2-2.
Time-solution (system output):
When undertaking the proportional control gain, K_pdesign using Root Locus within MATLAB, it is advisable that alongside this, you use MATLAB and perhaps Simulink to ‘investigate' the effect of the K_p values on the time-solution (system output).
Selecting a K¬_P value
You should select a proportional control gain, K_p that ‘best' meets the requirements and populate the relevant values in Tables 2-3 and 2-4. It might not be possible to meet the requirements. If this is the case, you should provide a comment to explain the finding(s).
In summary, in your coursework write-up, I expect to see the following figures and tables (with explanation) for your chosen proportional control gain, K_p:
Root locus plot (with the key features highlighted)
System response (time-solution, with this compared to the reference)
Tables 2-3 and 2-4 populated

This task builds on part b). You should now implement and tune a continuous-time PID controllerto ‘better' achieve your requirements given in Table 2-2.
When undertaking the PID controller design, the following should be considered/answered:
Determine the PID configuration needed and state why this has been selected
Investigate three variations of the controller gains (i.e., K_p,K_i and ¬K_d) on the system response. You should produce a table detailing the requirements (as given in Table 2-2), the controller gains and the results from the three variations. You should also select controller gain values such that the requirements of the DC motor control system are achieved.
Apply a disturbance (load) torque to your tuned control system. You should producea graphical output detailing the effect of the disturbance (i.e., compare this result to the unloaded DC motor control system). You should comment on the ability of your tuned controller to compensate for the disturbance (i.e., disturbance rejection).
Implement your tuned controller on the DC motor virtual lab (high fidelity model) - you should produce a video of your DC motor control system workingsuccessfully! Well done!
