Narrative:
I was the flying pilot on the ILS runway xxr at ZZZ. The winds had been reported as pretty gusty since we received our weather packet [at the departure airport.]last spring; on the same approach to the same runway with similar wind conditions I ran out of throw on the stick while landing and had to do a go-around. On our second attempt we got a wind shear alert and went around again; so this time I was ready for what I anticipated to be a difficult approach and landing.at approximately 200 feet AGL I encountered a gust from the left (winds were 240 at 13 gusting to 21 KTS). I sharply countered the gust using left stick; however I overcorrected and the plane rolled approximately 10 [degrees] to the left. I countered that roll with right stick; but also over corrected so the plane entered a similar bank angle to the right. I corrected for that with left stick and at that point realized I was encountering a pilot induced oscillation so I then centered the stick to get out of the oscillation. During the oscillation the spoilers had extended apparently causing us to get a bit low on profile.the captain said something like 'you're getting low.' at that point I noticed one white light and three red lights on the PAPI so I decreased my sink and said 'correcting.' the landing was fine and uneventful. After blocking-in I talked with the captain about the approach and my oscillation. He suggested that I hand fly the airplane more during gusty weather and disconnect the autopilot earlier during the approach (I disconnected it at minimums.) I plan on following this advice to help get a better feel for the winds effects on the plane.I think that because of my previous experience on that runway with gusty winds I was 'over-primed' to make corrections that in this case were too much.

Title: A320 First Officer landing during gusty crosswind conditions encountered pilot induced oscillations. Captain recommended hand flying the aircraft more during gusty weather and disconnecting the autopilot earlier during approach.
