A position control method, a position control device and an electric device and an electric device including the position control device are provided. The position control device includes a common motor (13), a performing unit (20) coupled to the motor to perform position change, a pulse generator (10) generating alterable pulse signals, a process unit (11) continuously collecting and processing the pulse signals and generating pulse width modulated signals, a coupling circuit (12) which connects the processing unit and the common motor and sends the pulse width modulated signals to the motor, the common motor receiving and performing the pulse width modulated signals and driving the performing unit to change its position. The position control device can perform real time open-loop control of position change.
