| 摘 要： | 将H-矩阵理论应用到传递函数对角优势化过程中,同时结合定量反馈频率自动整形原理,进行可重复使用亚轨道飞行器的多变量控制系统频域反馈补偿器的设计,从而达到削弱强耦合的目的。该方法通过使用H-矩阵理论,结合定量反馈考虑参数不确定性的优势,得到反馈补偿器的频域边界,因此,解耦结果对参数不确定性具有较强的鲁棒性。仿真验证表明,该方法有效地削弱了通道间的耦合,降低了控制器的设计复杂度。

| Abstract: | The feedback compensator of diagonal dominance in frequency domain for transfer function matrix of sub-orbital reusable launch(SRLV) vehicle based on the H-matrices and the automatic loop shaping of quantitative feedback theory(QFT) is presented.The feedback compensator based on the frequency bounds is designed by QFT,which is a robust method of considering the parameter uncertainty.This decoupling method is robust for the parameter uncertainty.The improvement of reducing the interactions and the order of the controller is verified by the simulation. |
