Abstract
A magnetic variable-damping vibration reduction control of a washing machine. A variable-damping shock absorber is arranged at the bottom of the outer barrel of a washing machine, one end of the variable-damping shock absorber is connected with the outer drum, while the other end is connected with a housing of the washing machine, and during stages with different rotating speeds, different currents are input into the variable-damping shock absorber, and the variable-damping shock absorber generates corresponding damping forces to reduce vibration, wherein in the vibration reduction process, the amplitude of vibration and the actual rotating speed of the motor are detected in real time, the difference between the actual rotating speed and the target rotating speed is calculated, and the size of the input current is adjusted in real time based on the amplitude of the vibration and the difference between the actual rotating speed and the target rotating speed.
