SimScope

Event Introduction

• Each team will comprise of 2 members at maximum.
• The event will be of a duration of <=2 hours.
• Useful knowledge for this event would include a bit of basic circuit analysis, basics of signal processing and a lot of common sense.
• Participants are required to develop their models based ONLY on the SIMULINK toolbox. Use of other toolboxes will not be allowed.
• Computers with MATLAB v7+ and SIMULINK v6.3+ will be provided.

Event Format

• Each question will have a fixed time limit for answering, which if exceeded will not be given credit.
• Bonus questions will be given if and when applicable.
• The first question to all teams starts with a common level of difficulty and the difficulty will increase when questions are answered correctly or difficulty will decrease when questions are forfeited or time limit is exceeded.
• A maximum of 5 questions can be forfeited.

Rules and Regulations

• Time is a major factor for model development and the fastest and most accurate models will be given more credit.
• The model will be evaluated based on various input parameters.
• The exact details about marking will be put up soon.
• Judges decision is final and binding.

Sample Questions

• You are working in your lab and the power at a particular switch point is cutoff as the fuse blows off. As there is no other free switch point available you bring in a small battery. From this battery you need to generate a triangular signal so as to continue decoding. Your task is to design a system that takes dc input and outputs a sine wave of frequency 50 Hz and of any amplitude. From this sine output, generate a square wave (with 0 dc) of frequency 100 Hz and amplitude equal to 5. Finally, using this square wave input, generate a triangular wave of frequency 100 Hz.
  • Notes:
  • For DC source, use the step input.
  • In case you cannot generate a sine signal from the step input, you may use the sine generator block to generate the square wave and the triangular wave subsequently. You would be given partial points (50%).
  • If you need a hint you can approach us. You will get 50% of your points in case the solution is right.
• Your task is to simulate this circuit with L1=0.5H, L2=0.2H, L3=0.1H and C=100uF. Set the frequency of the input sine signal as 94 rad/s and let its amplitude be 10V. Output the current flowing through the L2. You also need to tell us the specialty of the system?
