Bode tool computes a TF (transfer function) of Colink system with a selected simulation time. And then it makes a Bode diagram. State-space matrix is a residual when Bode makes TF. Bode diagram is a graphically dispalying method for frequency analysis. A variation of magnitude and phase delay is shown in logarithmic scales with growing frequency. When you use Bode tool, Colink system must be a RD plant block. Inputs of a Colink system are defined outputs of a RD plant block. And also, Outputs of a Colink system is the same inputs of a RD plant block. That s why it needs a RD plant block. First of all, Bode tool makes a state-space matrix in order to get TF. State-space matrix is as Eq 1. file://C:\Documents and Settings\xijiao\Local Settings\Temp\~hhE37E.htm 2009-4-17 PDF created with pdfFactory Pro trial version Bode
