Unformatted text preview: Behavior of Second-Order Systems Amber Mueller With Kyle Lowder Report No. ASE369K-ARM1 ASE-EM Department The University of Texas at Austin March 18, 2008 Abstract The behavior of a second-order system was examined as represented by an RLC circuit in W.R. Woolrich Laboratories at the University of Texas at Austin. In particular, the frequency response of a second-order system and the response to a step input were studied. At minimum damping ratio, the response to changing frequency was noted from 100 Hz to 1 kHz. This was repeated for a damping ratio of 0.7. The theoretical values for these cases were also found. A graphical comparison of the amplitude ratio and phase angle between experimental and theoretical values showed that, except for the phase angle at minimum damping, experimental results were closely aligned with theoretical results. Next, at minimum damping the function generator was set to input a square wave. The output was graphed against the input square wave for five different resistances....
