I don't think he is controlling Ichigo per se, but he is controlling Qangetsu, who is then in turn overpowering Ichigo for now. Been a while since Ichigo has chatted with either of his Zanpakuto in a while, as tends to happen in a major arc besides the whole "I've got this" doohickey with Oetsu, so would be a good time for the impossible fight, Zanpakuto chat, agree to work together, power up, thingy.
