1 Phase Margin Rule of Thumb
The phase margin is one of the robustness measures of a closed loop system under control. A low phase margin will lead to undesirable oscillations in the step response.
The phase margin can be determined from a:
1.1 Minimum Recommended Phase Margin
A good rule of thumb for the phase margin is
|Application||Minimum Phase Margin (deg)|
Please feel free to add the recommended minimum phase margin for the applications you are familiar with.
