Implementation of an Intelligent Control System

Abstract

A laboratory testbed facility which has been constructed at the NASA Lewis Research Center for the development of an Intelligent Control System (ICS) for reusable rocket engines is described. The framework of the ICS consists of a hierarchy of various control and diagnostic functions. The traditional high speed, closed-loop controller resides at the lowest level of the ICS hierarchy. Above this level resides the diagnostic functions which identify engine faults. The ICS top level consists of the coordination function which manages the interaction between an expert system and a traditional control system. The purpose of the testbed is to demonstrate the feasibility of the ICS concept by implementing the ICS as the primary controller in a simulation of the Space Shuttle Main Engine (SSME).
