General aviation digital autopilot design based on LQR/LQG control strategy

Abstract

The paper introduces a description of a Linear Quadratic Regulator (LQR) / Linear Quadratic Gaussian (LQG) controller design along with related basic theory. The LQR/LQG controller of a digital autopilot is subjected to performance evaluation tests, which consider various performance and stability requirements issued by the regulatory agencies. The design's robustness is tested on a General Aviation aircraft simulation model.
