基于定量反馈理论的弹道导弹俯仰通道姿态控制系统设计

摘要

Quantitative Feedback Theory (QFT) is a robust control design method based on frequency domain, which can meet the robust demand of uncertain systems and be easily carried out in engineering applications. The ballistic missile pitching channel attitude control system with model uncertainty is considered in the design based on QFT in this paper. The results of performance validating and time domain simulating indicate that the QFT system performs well on robust demand and celerity.%定量反馈理论（QFT）是一种既能满足不确定性系统的鲁棒性要求，又在工程应用中易于实现的基于频域的鲁棒设计方法。基于QFT设计考虑弹体不确定性的弹道导弹俯仰通道姿态控制系统，性能验证与时域仿真结果表明，所设计的QFT控制系统具有良好的鲁棒性和快速性。
