NOZZLE RING POSITION SELF-LEARNING METHOD, AND METHOD AND APPARATUS FOR DETERMINING OPENING DEGREE OF NOZZLE RING

WIPO Patent Application WO/2021/228002

A1

A nozzle ring position self-learning method, and a method and apparatus for determining an opening degree of a nozzle ring. The nozzle ring position self-learning method comprises: separately obtaining top and bottom dead center feedback voltages of the mechanical top and bottom dead center positions of a nozzle ring; when the top and bottom dead center feedback voltages respectively are within first and second preset voltage ranges, determining that the top and bottom dead center feedback voltages are voltages when the nozzle ring is fully opened and fully closed; according to the voltages when the nozzle ring is fully opened and fully closed, calculating a slope value of the opening degree percentage and the voltage of the nozzle ring in a movement range from being fully closed to being fully opened or from being fully opened to being fully closed; and when the slope value is within a preset slope range, determining that the self-learning of the position of the nozzle ring is completed.
