Modal Control Theory and Application to Aircraft Lateral Handling Qualities Design

摘要

A multivariable synthesis procedure based on eigenvalue/eigenvector assign¬ment is reviewed and is employed to develop a systematic design procedure to meet the lateral handling qualities design objectives of a fighter aircraft over a wide range of flight conditions. The study reveals that the closed-loop modal characterization developed provides significant insight into the design process and plays a pivotal role in the synthesis of robust feedback systems. The simplicity of the synthesis algorithm yields an efficient computer-aided inter¬active design tool for flight control system synthesis.
