Method for determining the position of an element driven by the drive shaft of a direct current motor |
摘要 |
A method for determining the position of a movable element to be driven by a direct current motor between first and second positions includes counting ripples contained in a motor current signal as the motor rotates to drive the element. The position of the element is determined based on the counted ripples. The motor actuates, until the current signal is void of ripples, to move the element into the first position when the element is to be moved out of the first position towards the second position. The counted ripples is reset to a reset value after the motor has been actuated to move the element into the first position such that the reset value corresponds to the position of the element being in the first position. The motor actuates to move the element towards the second position after the counted ripples has been reset.
