Abstract
A system for obtaining collective decisions from multiple control sources. The system is able to produce a single command from these control sources. Each control source corresponds to a behavior and each responds to inputs to produce a command. The system employs a piece-wise constant preference profile composed of zones, spikes, and clamps which compress the amount of the amount of data required to process behavior preferences. The system sorts commands according to command values in a chart to produce a total profile which represents the combination of profiles of the command values for multiple behaviors. The peak zone in the total profile is then used to produce a desired response to the multiple commands. The system allows behaviors to be combined through command fusion rather than subsumption. The piece-wise constant representation allows behavior commands to be combined after they have been passed through a standard control system. This permits behaviors to use any derivative of the control source's variable that is appropriate for their function. The system has a bounded arbitration time so that control loop stability will not be disrupted by the arbitration process. The s…
