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。 The H-matrix theory is applied to the diagonal optimization of transfer function. At the same time, with the principle of quantitative feedback frequency auto-shaping, the design of frequency-domain feedback compensator for multivariable control system of reusable sub-orbiter can be achieved, the goal of. The method obtains the frequency domain boundary of the feedback compensator through the use of H-matrix theory and the quantitative feedback considering the advantages of the parameter uncertainty. Therefore, the decoupled result has strong robustness to parameter uncertainty. Simulation results show that this method effectively weakens the coupling between channels and reduces the design complexity of the controller.
