[PDF] Top 20 Lab 2: Time Domain Modeling of One Degree of Freedom Systems

... This part of the lab should be done independently of Part 2. That is, do not just use the values for the natural frequency ω n and damping ratio ζ y ou obtained from the log- decrement method. Part of the ... See full document

... 7) Modify the values of the static gain, then the damping ratio, and then the natural frequency to try and get the model to match the system as closely as possible during the first part of the step (it is likely to get ... See full document

... u t = A ω t where, for out systems, A is measured in radians or degrees. After a transition period, the steady state output will be θ 1 ( ) t = B cos( ω ψ t + ) , where B is also measured in cm. Since we will be ... See full document
