General Questions
Post general questions or requests for clarification here.
- For the 2008 test, problem III, part d, is the reasoning in the answer key that the calculated value for \(\omega_d\) is too different from \(\omega_n\), so the extra zero/pole have an effect? Nbb5 22:56, 24 March 2009 (EDT)
- Should we know how to use the equation that solves the phase space matrix, \(\frac{Y}{U}=C(sI-A)^{-1}B+D\)? Nbb5 22:56, 24 March 2009 (EDT)
