Jet Engine Simulator as a 1st Order Control Experiment

Create M-file in MATLAB 1. Convert time in minutes to time in seconds. Adjust so recording starts at t=0 seconds. Alternatively, may set t=0 when thrust level step starts.

2. Create two graphs (Step up and Step down). Each with two curves. The Desired low compressor speed (rpm) vs. time, and actual low compressor speed (rpm) vs time. (I.e., NL_Setpoint(rpm) vs time and NL(rpm) vs time.)

3. . You will need to calculate what NL rpm speeds corresponds to 10% and 90% of the change in rpm (between low thrust to max thrust speeds) at each altitude.

4. You will need to account for the non-zero rpm before the recording starts, and the step input occurring sometime after t = 0 seconds.

5. Calculate the Rise Time (seconds), that is time it takes to go from 10% to 90% of final value (NL rpm speeds), assuming this is a 1st order (DO NOT Calculate the rise time of the PLA% if you recorded that variable.) system.

6. Calculate the System Time Constant and Settling Time (for all the variables we are assuming this is a 1st order system response to a step input).

7. Repeat the calculations for the stepdown thrust.

8. Add a text box on an identified tab in your sheet, and in a paragraph or two explain the effects stepup and down rise time and other specs if any.

9. Use MATLAB figures and copy code and graphs to Word doc and add comments.
