| 摘 要： | 应用鲁棒稳定性理论，对颤振主动抑制系统进行了分析研究，通过分析和计算气动弹性闭环系统回郑矩阵的最小奇异值，判定系统的稳定性系统抗扰动的不灵敏特性。文中以一小展弦比机翼／外挂颤振主动抑制系统模型为例，进行了分析和计算。并应用约束变尺度法，对控制律重新进行了综合优化设计，使得该系统的稳定裕度，抗扰动的不灵敏性及低速稳定性有所改善。

| Abstract: | Robust stability theory is used to study the flutter active suppression system. Through the analysis and calculation of the minimum singular value of the aeroelastic close-loop system return difference matrix(RDM),it evaluates the system stability,insensitivity to disturbance. As an example,a lowaspect-ratio wing/stor flutter active control system is analyzed by applying CVM(Constrained Variable Metric) method to control law synthesis and optimization design. It has advanced the system control law,and thereby has improved the system robust stability,insensitivity to disturbance and low speed stability. |
