摘　　要：针对双通道控制高超声速飞行器横侧向欠驱动、强不确定性的特点,研究了适用于工程应用的控制策略,提出一种基于特征根有界摄动分析的反馈控制鲁棒性分析方法。基于线性化近似分析和工程约束需求,给出了双通道飞行器改善荷兰滚模态动态的2种控制策略,分别为极点配置方案和模态解耦方案。提出了特征根灵敏度矩阵和有界摄动矩阵的概念,用于评估闭环系统对参数不确定的鲁棒性。基于闭环六自由度模型在标称及参数拉偏情况下,对2种方案进行了综合分析和仿真验证。仿真结果表明,2种控制方案均可以解决双通道控制问题,所提特征根有界摄动分析方法可准确评估系统的鲁棒性。Considering the underactuated hypersonic flight vehicles with strong uncertainty of the dual channel attitude control strategy,practical feedback-based dual-channel control schemes are given and the ro-bustness analysis method based on the bounded perturbation analysis of eigenvalues is proposed.Firstly,two control schemes,namely the pole-assignment schemes and modes-decoupling scheme,are given to improve Dutch roll dynamics based on the approximate linearization approach and engineering constraints.Then,to evaluate the robustness of the closed-loop system for the uncertain parameters,the eigenvalue sensitivity matrix,the eigenvalue bounded-perturbation-matrix and eigenvalue bounded-perturbation index are proposed.Finally,simulations and analysis of the proposed schemes and methods are given based on the closed-loop six degree-of-freedom model with nominal parameters and perturbed parameters,respectively.Simulation results demonstrate that both schemes could solve the dual-channel control issue.The results also show that the per-turbation analysis of eigenvalues could precisely evaluate the system robustness.
