发明名称 METHOD AND DEVICE FOR CONTROLLING A HYDRAULIC ACTUATOR
摘要 A method, device, and control unit for controlling an actuator in open loop, particularly for a valve, preferably for a gas-exchange valve of an internal combustion engine, having at least one control valve for opening the valve and one control valve for closing the valve, each of the control valves being capable of being driven by at least one drive pulse whose duration determines a position on the positioning travel of the valve. The valve is opened/closed in one lift and/or a plurality of partial lifts and at least one drive pulse is assigned to each lift and/or each partial lift, and the valve is assigned at least one transducer which generates a signal that discloses values of a discrete positioning travel of the valve and of an assigned time and/or of a discrete instant and of an assigned positioning travel. The method for controlling the actuator includes: a. Starting of a drive pulse having a setpoint duration of the drive pulse for opening and/or closing the valve, b. Generating at least one signal, and c. Correcting the setpoint duration of the drive pulse and/or of a following drive pulse assigned to the lift and/or to a partial lift, in accordance with the signal.
