Delay Margin

Topics: Feedback Control Systems

The delay margin answers the following question:

How much delay can the closed-loop system tolerate before it reaches the verge of instability?

The delay margin is measured at the unity-gain crossover frequency ω\omega and is related to the Phase Margin as follows

DM=PM×π180ωDM = \frac{PM \times \frac{\pi}{180}}{\omega}
