Table 6 Comparison of stability analysis in analog domain of BBC in buck mode of operation
System | PM (degrees) | GM (db) | ωg (rad/s) | ωp (rad/s) | Delay margin (s) | Stability state |
|---|---|---|---|---|---|---|
Open loop (withoutpid) | Inf | Inf | Inf | Inf | Inf | Stable with poor dynamic response |
PID control (analog_Cloop) | 129 | 4.81 | 6330 | 354 | 0.00636 | Stable with good dynamic response |
PIDN control (analog_CloopN) | 122 | 40.8 | 5740 | 360 | 0.0059 | Better stable with good dynamic response |
