摘要
提出了一种M IM O定量反馈理论与特征值配置相结合的鲁棒解耦控制方法,该方法首先利用特征值配置使系统达到性能指标要求,通过对特征向量的限制实现M IM O系统解耦,然后利用QFT方法使其具备鲁棒性。通过对某型飞机侧向通道的仿真表明:该方法不仅解耦效果良好,而且具有较强的鲁棒性。
An approach to robust control design for a lateral flight control system using eigenstructure assignment (EA) and quantitative feedback theory (QFT) is introduced. The eigenvalues in EA determine the decay/growth rate of the corresponding states. Eigenvectors coupling relations among various states. The QFT method is used to obtain robust stability. The design results demonstrate the good performance and robust features of the proposed EA/QFT approach that may be achieved.
