| 摘要 |
The present invention relates to an electrohydraulic control apparatus (1) having a hydraulically operable, proportionally adjustable actuator (8), having an electrically actuable pressure-reduction valve (7) whose output (14) forms a fluidic connection with a control-pressure connection of the actuator, having control electronics (10) to one of whose inputs a setpoint signal which prespecifies an degree of actuation of the actuator can be supplied, and having a driver circuit (40) which generates an electrical actuating signal for the pressure-reduction valve on the basis of an input signal. The control electronics, the driver circuit, the pressure-reduction valve and the actuator are arranged in the form of a control chain. The control electronics have a correction circuit (22, 23, 24, 26) for generating a correction signal. The correction signal can be used to modify the setpoint signal in order to reduce a dynamic lag error between the setpoint signal and an actual degree of actuation. The modified setpoint signal is supplied to the driver circuit as an input signal. |
