He performed the action in a very controlled way.
💡'controlled' here is not a passive of 'control'; use it as a descriptive adjective in front of the action noun.

用法筆記

Strictly attributive in this sense, modifying 'study', 'trial', 'experiment', or 'conditions'. Often paired with 'randomized' in medical research ('randomized controlled trial'). Distinguish from sense 1: a 'controlled descent' is a careful action; a 'controlled trial' is a designed comparison.

💡the experiment is the thing being kept under control, so use 'controlled', not 'controlling'.
