# Assignment 2

- Consider Figures 3.3 and 3.4 in CCS. Determine how the Nyquist and Bode plots are changed with the sampling period. Hint: The Matlab macros for all simulations in CCS are available.
- Consider Problem 7.7. Where is the folded frequence when it looks as if the wheel is rotating backwards?
- Consider Example 3.6 and Figure 3.9. Pick three different locations of the eigenvalues of the Phi-matrix and determine how the trajectories are changing. Hint: Which are the interesting parts of the stability triangle in Figure 3.2?
