Explanation
Something that's controlled is kept in check or restrained. Your controlled laughter in math class won't get you in trouble, because it's muted and calm. Some people really blow their stacks when they get angry, while others express a controlled anger, calmly explaining their frustration. The ability to keep your emotions controlled is a useful one.
