PURPOSE: A pulsator driving method is provided to control the pulse width modulation efficiency ratio and a lead angle in the proportional integration control for precisely control the pulsator, thereby increasing the washing performance while reducing the damage of the clothing. CONSTITUTION: A pulsator driving method includes an initiating step of determining an initial pulse width modulation efficiency ratio and an initial lead angle by sensing the load of clothing(S100), and a control step of determining a pulse width modulation efficiency ratio and a lead angle on the bases of the initial pulse width modulation efficiency ratio and the initial lead angle for controlling the motor in case of acceleration performance(S200). |
