| 摘要 |
The invention relates to a driver circuit for an electrical actuator (1), especially for an electromotively activated exhaust gas valve of an internal combustion engine, comprising a first signal input for receiving a setpoint value (XSET) for the actuator position, a second signal input for receiving an actual value (XACT) for the actuator position, a signal output for releasing a control variable (FG) for the actuator (1) and a regulating unit (6) for determining the control variable (FG) for the actuator in dependence on the deviation between the setpoint value (XSET) and the actual value (XACT), this regulating unit being connected to the two signal inputs on the input side and to the signal output on the output side. A control unit (5) that is connected to the first signal input on the input side is provided and determines the control variable for the actuator (1) in dependence on the setpoint value (XSET) of the actuator position. |
