You could look at it that way.

The proportional part responds immediately and aggressively to large errors, but is satisfied once the error is "sufficiently small"*. The integral part makes relatively slow corrections, even to large errors, but doesn't give up until the error is essentially zero.


*how small is "sufficiently small" depends on how high you have the gain turned up for P.
