About Peak-Valley Compensators (PVC)
Peak/Valley Compensation (PVC) monitors cyclic command feedback for any amplitude roll-off or mean-level
divergence.
• PVC increases the command amplitude if it detects amplitude roll-off in the feedback signal.
• PVC adjusts the mean command level if it detects mean-level divergence in the feedback signal.
Note:
For best results when using PVC, set the I Gain as low as possible on the control mode being
compensated. Setting I Gain too high may result in system instability.
