Agricultural sprayer having a sprayer linkage and a chassis which is supported on the ground and can be moved over a field in a forward direction, wherein: - the sprayer linkage comprises a central segment movably supported on the chassis and two booms respectively arranged on a side of the central segment, which can each be pivoted by an actuator with respect to the central segment about an axis extending in the forward direction, - the actuators can be controlled by a control device, which can be supplied with signals provided by sensors with regard to the relative position of both booms with respect to a field contour, and which can be operated to control the actuators on the basis of the signals with the effect of maintaining the positions of the booms in a desired position over the field contour, an adjustment of one actuator also results in a movement of the respective other boom because of the mechanical coupling of the booms by the central segment, and the control device comprises a multivariable controller, which can be supplied with the signals from both sensors as input variables and which is set up to provide control signals for both actuators, each of which depends on both input variables, and which considers the mutual influence of the actuators when calculating the control signals, characterized in that the central segment can be adjusted with respect to the chassis about an axis extending in the forward direction by a third actuator, the control signal of which can be provided by the multivariable controller as a function of both input variables, and in that the multivariable controller can be supplied with a further input variable, which represents the sensor-detected angle of the central segment with respect to the field contour, and the multivariable controller can be operated to create the control signals of all the actuators (40, 48) in each case as a function of all the input variables. - the sprayer linkage comprises a central segment movably supported on the chassis and two booms respectively arranged on a side of the central segment, which can each be pivoted by an actuator with respect to the central segment about an axis extending in the forward direction, - the actuators can be controlled by a control device, which can be supplied with signals provided by sensors with regard to the relative position of both booms with respect to a field contour, and which can be operated to control the actuators on the basis of the signals with the effect of maintaining the positions of the booms in a desired position over the field contour, an adjustment of one actuator also results in a movement of the respective other boom because of the mechanical coupling of the booms by the central segment, and the control device comprises a multivariable controller, which can be supplied with the signals from both sensors as input variables and which is set up to provide control signals for both actuators, each of which depends on both input variables, and which considers the mutual influence of the actuators when calculating the control signals, characterized in that the central segment can be adjusted with respect to the chassis about an axis extending in the forward direction by a third actuator, the control signal of which can be provided by the multivariable controller as a function of both input variables, and in that the multivariable controller can be supplied with a further input variable, which represents the sensor-detected angle of the central segment with respect to the field contour, and the multivariable controller can be operated to create the control signals of all the actuators (40, 48) in each case as a function of all the input variables. an adjustment of one actuator also results in a movement of the respective other boom because of the mechanical coupling of the booms by the central segment, and the control device comprises a multivariable controller, which can be supplied with the signals from both sensors as input variables and which is set up to provide control signals for both actuators, each of which depends on both input variables, and which considers the mutual influence of the actuators when calculating the control signals, characterized in that the central segment can be adjusted with respect to the chassis about an axis extending in the forward direction by a third actuator, the control signal of which can be provided by the multivariable controller as a function of both input variables, and in that the multivariable controller can be supplied with a further input variable, which represents the sensor-detected angle of the central segment with respect to the field contour, and the multivariable controller can be operated to create the control signals of all the actuators (40, 48) in each case as a function of all the input variables.
