Abstract
A fuzzy logic load management controller for use with a computer image generator. The load management controller is used use with a computer image generator having a plurality of inputs and a plurality of outputs, and includes an adder that couples inputs to the image generator. The load management controller comprises a fuzzy logic controller disposed in a feedback loop between the output of the image generator and the adder. The load management controller includes a fuzzy logic inference engine, a set of membership functions coupled to the inference engine, and a rules database coupled to the inference engine that includes a set of if-then rules that specify the response of the fuzzy logic controller to inputs applied thereto. The fuzzy logic controller provides for load management of the image generator that gracefully degrades a viewed scene, keeps the image update rate constant, and renders important objects in the viewed scene.
