Optimal phase margin
WebFrom the analytical expression of G op (s), it can be found that the gain margin and phase margin have the same signs. Therefore, the positive gain margin is set as the first constraint with phase margin ensured accordingly. ... The gain margin corresponding to the optimal point is about 4.57 dB. According to the proposed design method, the ... WebPhase Margin — Specify a target phase margin for the system. To reduce overshoot and create a more robust controller, increase the phase margin. To apply the specified controller design to the selected compensator, …
