METHOD FOR DETECTING AND CONTROLLING MOVEMENT OF AN ACTUATED COMPONENT

摘要

A method for detecting and controlling the position of a valve actuator (10) is provided. The method includes applying a plurality of signals of different duration and/or magnitude to the valve actuator (10) and measuring a signal from the valve actuator (10). This signal from the valve actuator (10) is indicative of valve movement for each of the plurality of applied signals. The method further includes adjusting an injection signal to the valve actuator (10) based at least from the measured signals from the valve actuator (10). This disclosure also applies this method to a solenoid actuator of a fuel injector.
