Laundry treatment apparatus and method of controlling the same

A method of controlling a laundry treatment apparatus comprising:

• a drum configured to rotate within the laundry treatment apparatus and to accommodate laundry therein, the drum formed of a metal material;
• an induction module configured to be spaced apart from an outer circumferential surface of the drum and configured to heat the drum via induction using a magnetic field that is generated in a state in which current is applied to a coil in the induction module;
• a lifter that is provided in the drum and that is configured to revolve around an axis of rotation of the drum and to agitate the laundry inside the drum as the drum rotates;
• and a module controller, comprising at least one processor, that is configured to control an output of the induction module to control an amount of heat generated at the circumferential surface of the drum, the method comprising:
• operating the induction module to generate the magnetic field;
• controlling, by the module controller, the induction module to generate a first output;
• determining a position of the lifter as the drum rotates;
• and
• determining whether to reduce, by the module controller, the output of the induction module from the first output to a second output based on the position of the lifter that is determined.
