Abstract

A knowledge-based system called the Control Laws Expert Assistant for Rotorcraft (CLEAR) was developed to help flight control engineers design laws that allow linearized mathematical models of rotorcraft to meet performance criteria as specified in MILSPEC MIL-H-8501B. The system designs compensators that, when coupled with linear, time-invariant, single-input, single-output, continuous plants, will meet the set of prescribed performance specifications. A modular, hierarchical, knowledge-based system designed using an expert system shell which interacts dynamically with a computer-aided control system analysis package is described. A design problem is presented for illustrative purposes
