uiz #2 Bode Diagrams For questions 1 and 2 11/9/16 Due 11/14/16 s s 1 1 (s) 0.0605 0.535 0.618 e s s 2 2 0.0606 s 2 2 0.522 s 1 s 1 0.1635 0.1635 1.619 1.619 (1) Use the graphical technique to determine the Amplitude Ratio and Phase Angle for the Pitch Angle per minus elevator deflection. (2) Show how you would correct the Amplitude and Phase Angle using the charts provided in this document. For questions 3 and 4 s 1 (s) 0.535 0.618 e s s 2 2 0.522 s s 1 1.619 1.619 (3) Using the short-period approximation of pitch angle per minus elevator deflection and calculate the Amplitude Ratio and Phase Angle by substituting for s = j. (Hint: I would suggest an EXCEL or other spreadsheet.) (4) Compare the Bode diagrams of the two transfer functions above using Matlab. MAE 4310 Introduction to Automatic Control Instructor Dr. B.R.
