Abstract
A washing machine includes a drum, a drum motor coupled to the drum; a driving circuit and a processor. The driving circuit is configured to supply a driving current to the drum motor so that the drum motor rotates. The processor is configured to control the driving circuit to accelerate the drum motor from the first rotational speed to a second rotational speed based on a gradient of the fluctuating magnitude of the driving current supplied to the drum motor while controlling the driving circuit to rotate the drum motor at a first rotational speed.
