Abstract : This report deals with the problem of automatic, external control of an underwater vehicle such that it obeys an intercept guidance law while remaining outside a region defined relative to a time varying measurement. The approach herein uses fuzzy set theory to develop a hierarchical controller that deals with multiple competing goals and determines the necessary commands to be sent over a two way communication link between the launching platform and the vehicle being guided. Control of the vehicle entails use of a time varying data input stream from the launching platform sensor. The controller is implemented in a simulation to demonstrate and analyze performance.
