Summary of Root Locus Design Uses time domain specifications (e.g., settling time, % OS, etc.) to specify desired root locations of closed-loop characteristic equation. Achieving desired time-domain performance Slide 1 ME 475 Session 14: Frequency Domain Design Galen King Purdue University depends on validity of the 2 nd -order dominance assumption and absence of “slow” zeros. Only closed-loop poles can be placed; closed-loop zeros cannot be directly manipulated. Frequency-dependent effects hard to incorporate.
