1. An agricultural mobile machine, comprising: a plurality of different sensors, each sensing a different variable and generating a corresponding sensor signal indicative of the sensed variable; a plurality of different controllable subsystems; a probabilistic controller configured to receive the sensor signals and generate a set of estimated variable values for unobserved variables and generate a plurality of different subsystem control signals to control the plurality of different subsystems, based on the sensor signals and the estimated variable values for the unobserved variables, wherein the probabilistic controller comprises a probabilistically inferred value generator that generates the estimated variable values for the unobserved variables; a control signal generator that generates the plurality of different subsystem control signals: and a material processing system that processes material in a harvesting operation and wherein the probabilistically inferred value generator comprises: a material stream volume estimator component that generates estimated values indicative of material volumes at different places in in the material processing system during the harvesting operation: and a crop behavior characteristic estimator component that generates estimated values indicative of processing characteristics of a crop being harvested during the harvesting operation.
