샘플링 시간에 대해 개선된 Singular Perturbation 기반 STT missile 디지털 autopilot 설계

Design of an improved STT missile digital autopilot with respect to sampling time

In this paper, we investigate the time-sampling effects on the digital implementation of singular perturbation based STT autopilot with excellent performance and propose a compensation method for the time-sampling effects. In digitization of analog STT autopilot, it is found that the stability margin of the fast dynamics is mostly affected to lead to rapid decrease. Under the this analysis, a composite digital controller with additional compensator for fast dynamics is proposed to improve the time-sampling effect and a simulation verifies the result.
