Consistency Diagram with Final Autonomous Estimates Figure 21. Auto-MAC of Final Autonomous Estimates - Conjugate Poles While the results are certainly acceptable for this case, the Auto-MAC plot in Figure 21 shows some additional clutter and the conjugate properties of the higher frequency modes do not match as well as in the previous, long dimension base vector example.
