| 20090299496 | Controller - A controller is provided, operable to control a system on the basis of measurement data received from a plurality of sensors indicative of a state of the system, with at least partial autonomy, but in environments in which it is not possible to fully determine the state of the system on the basis of such sensor measurement data. The controller, comprises: a system model, defining at least a set of probabilities for the dynamical evolution of the system and corresponding measurement models for the plurality of sensors of the system; a stochastic estimator operable to receive measurement data from the sensors and, with reference to the system model, to generate a plurality of samples each representative of the state of the system; a rule set corresponding to the system model, defining, for each of a plurality of possible samples representing possible states of the system, information defining an action to be carried out in the system; and an action selector, operable to receive an output of the stochastic estimator and to select, with reference to the rule set, information defining one or more corresponding actions to be performed in the system. | 12-03-2009 |
