LSS Attitude Control Experiment

Application of LQ Loop-Shaping Capability

Abstract

This paper studies the LQ regulator loop shaping capability in order to enhance the LSS stability robustness, experimentally. To this end, a frequency-dependent optimal regulator gain is designed to give the low-pass property to the loop transfer function in a LQ framework. Then a state estimator is constructed to preserve its property in a Loop Transfer Recovery manner. A ground-based experiment is performed by utilizing a single-axis air-table.
