Application of a LISP (List Processing Language) Based Expert System for Failure Diagnosis of the CH-47 Flight Control Hydraulic System

摘要

An investigation of the hydraulic flight control system of a Boeing CH-47 Chinook helicopter utilizing artificial intelligence techniques will be undertaken. Specifically, a knowledge based expert system will employ situation-action rules (production rules) to diagnose a failure and subsequently identify specific devices(s) which caused that failure. Moreover, because the behavior of the system is directly responsive to the goals the system is attempting to achieve, the expert system's inference engine performs a backward-chaining process via a goal-driven control strategy. The List Processing Language (LISP) is used to facilitate data processing and symbolic logic expression.
