Abstract
A controller for a machine may receive an activation command to activate a metering operation that is to vibrate an implement of the machine by repetitive changing of at least one of an angle or a position of the implement. The controller may generate, while the metering operation is ongoing, a metering control signal for the metering operation by adjusting a baseline metering signal in accordance with sensor data relating to a characteristic of the implement. The controller may cause actuation of an implement actuator for the implement in accordance with the metering control signal.
Claims21
A control system for an implement of a machine, comprising:
- one or more sensors configured to detect an angle of the implement;
- an implement actuator configured to actuate the implement;
- and
- a controller electrically connected with the one or more sensors and the implement actuator, the controller configured to:
- receive an activation command to activate a metering operation that is to vibrate the implement by repetitive changing of at least one of the angle or a position of the implement;
- obtain, from the one or more sensors and based on receiving the activation command, sensor data indicating a current angle of the implement at a time of activation of the metering operation that defines a target angle for the implement;
- generate, while the metering operation is ongoing, a metering control signal for the metering operation by generating an implement movement signal for returning the implement to the target angle in accordance with a difference between the angle of the implement, indicated by the sensor data, and the target angle for the implement, and scaling a baseline metering signal by gradually adjusting a magnitude component of the baseline metering signal based on the implement movement signal;
- and
- output the metering control signal, to the implement actuator, to cause actuation of the implement actuator in accordance with the metering control signal.
