Abstract
A method of controlling the weight of bales made by an agricultural baler. The method includes: receiving a bale weight setpoint; receiving crop parameter data; and, while a bale is being made: receiving baler operating data relating to baling parameters; inputting the crop parameter data and baler operating data into a weight prediction model to generate a predicted final weight of the bale; and changing a baling parameter setpoint of one of the baling parameters based on the predicted final weight of the bale and the bale weight setpoint.

A method of controlling the weight of bales made by an agricultural baler, the method comprising:
- receiving a bale weight setpoint;
- receiving crop parameter data;
- and,
- while a bale is being made:
- i) receiving baler operating data relating to baling parameters;
- ii) inputting the crop parameter data and the baler operating data into a weight prediction model to generate a predicted final weight of the bale;
- iii) changing a baling parameter setpoint of one of the baling parameters based on the predicted final weight of the bale and the bale weight setpoint, and
- iv) repeating steps i), ii), and iii) while the bale is being made,
- wherein steps i), ii), and iii) are repeated every time n slices of the bale have been completed, and
- wherein the baler operating data is received for previous m slices of the bale, wherein n is greater than or equal to m.
A method of controlling the weight of bales made by an agricultural baler, the method comprising:
- receiving a bale weight setpoint;
- receiving crop parameter data;
- and
- while a bale is being made:
- receiving baler operating data relating to baling parameters;
- inputting the crop parameter data and the baler operating data into a weight prediction model to generate a predicted final weight of the bale;
- changing a baling parameter setpoint of one of the baling parameters based on the predicted final weight of the bale and the bale weight setpoint, and
- adjusting the weight prediction model, wherein adjusting the weight prediction model includes:
- measuring a final weight of the bale using a bale weight sensor;
- calculating a difference between the measured final weight of the bale with the predicted final weight of the bale;
- calculating a model offset in dependence on the difference between the measured and predicted final weights of the bale;
- and
- applying the model offset to the weight prediction model.
