【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。更多还原

【Abstract】 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 robustness 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 perturbation analysis of eigenvalues could precisely evaluate the system robustness.更多还原
