the person who cast the curse can take control of the person who is cursed
Well it depends. If Harry Potter were to bewitch someone to make them do whatever he wanted he could use the imperius curse. The verbal command would be "imperio". The imperius curse is one of the three unforgivable curses and is against wizard law in the Harry Potter series. Beyond that there are many different spells to bewitch all sorts of objects in various different ways.
Although we never see an example of this we do see Harry blocking the killing curse with Expelliarmus which is considered less advanced than Protego so it is quite likely.
That was the class - to learn to resist the imperious curse. Presumably "Professor Moody" got a special permission to use the otherwise forbidden curse. He repeatedly put the curse on Harry because Harry was the only student showing some sign of immunity against it and 'Moody' was determined to make him be able to throw it off completely. It can also be argued that he just wanted to hurt Harry since he was actually Barty Crouch Jr.
The Imperio spell in Harry Potter is the spell that casts one of the Unforgiveable curses-the Imperius curse. Whoever casts this spell will have control over that person/thing and can make that person do whatever the caster wants him/her to do. There are ways of blocking the spell, however, as Harry proves in the Goblet of Fire when the fake Mad-Eye Moody puts the spell on him to see if he can fight it. The other Unforgiveable curses are Crucio (the torture curse) and Avada Kadavra (the killing curse).
He was under the Imperius Curse.
Yes she has. In the Goblet of Fire Professor Moody put the Imperius Curse on everyone in the class to see if they could fight it off. Harry was the only one who could.
Harry Potter has used two unforgivable curses. In the Order of the Phoenix he used the Cruciatus curse on Bellatrix Lestrange, then in the Deathly Hallows he used the Imperius curse to break into Gringotts.

The Unforgivable Curses in Harry Potter are: the Cruciatus Curse, the Imperius Curse and Avada Kedavra. Cruciatus Curse: (Crucio!) to cause someone great pain. Imperius Curse: (Imperio!) used to give a command to someone, and the victim cannot do anything but to obey (some people that have a weak will can succumb easily). Avada Kedavra: (Avada Kedavra!) instantly kills the victim.
The three unforgiveable curses are Cruicatus curse, the torture curse, Imperius curse, gives you full controll over another, and then the Killing curse (Avada Kedavra), is the curse that kills. SLS
Imperius (control the mind of the victim), Cruciatus (torture), Avada Kedavra (the killing curse).
The most famous curse in the Harry Potter franchise is most likely the Killing Curse, which has the incantation Avada Kedavra. It is the signature spell of the series' antagonist Voldemort and is one of three Unforgivable Curses, the other two of which are the Imperius Curse (Imperio) which renders a victim under the castor's control, and the Cruciatus Curse (Crucio) which causes intense pain.
Although we never see an example of this we do see Harry blocking the killing curse with Expelliarmus which is considered less advanced than Protego so it is quite likely.
