Bismihi ta'ala
I am sure you know that in Islam, becoming an "adult" is not defined by turning 18 or 21. We see maturity to be reaching the age of taklif, where we become religiously responsible and accountable.
As Muslims, we also know that obedience to parents has no age limit, and we show our utmost respect and reverence to our parents, as old as we get. The status of parents is above everything, and that is why you should not see it to be "control" in the negative sense.
Parents have authority over us, and in most, if not all cases, they want the best for us. As we grow, we must increase in our level of obedience to our parents, and cater for them as much as possible. We show this to ourselves, and to our children, so our children will learn from us. When we get old, we wont need to struggle, because we have shown our children the right Islamic way of how to treat elders.
You must not disobey your parents, and always try your best to comply to their requirements and keep them happy with your behaviour and what you do. Please read about what our religion says about parents and the abundant reward we get in this dunya and akhirah when we show our obedience to them.
Of course, we are talking about normal situations, but if one's parents are indeed evil, abusive and negatively controlling, then that would need to be dealt with in a wise way.
With prayers for your success.
