Abstract
An algorithm calculates a correction value to be applied to a slot in an adjustment period for power correction. For each slot, the algorithm determines whether adding a correction value in a given slot would bring the actual accumulative adjustment value closer or farther from an accumulative adjustment target value. The accumulative adjustment target value has a linear relationship with the slot number and is calculated for each slot to ensure that any corrections are evenly distributed over the adjustment period for a smooth correction. In one embodiment, the algorithm also checks the total amount of adjustment applied to the slots over a sliding adjustment window to make sure that the total amount of adjustment applied to the slots in the adjustment window do not exceed a predetermined maximum threshold.
