摘要
对颤振主动抑制控制律的优化设计进行了研究．提出了一种基于“极点配置”思想，考虑低速稳定性的工程性控制律初值设置方法；在优化过程中，除考虑阵风响应等约束外，还考虑了鲁棒性问题．以某型飞机的动力相似模型为实例进行计算．计算结果表明，设计的优化控制律能有效抑制颤振，保证低速稳定性。
An optimal design technique of active flutter suppression control laws is studied. An engineering initial value design method,which is based on the idea of fold pole configuration and considers the slow speed stability,was proposed;and the robustness was considered in the optimal process besides gust response constrainted.According to the method mentioned above, an optimal control law was explored to a dynamic model of a type of aeroplane.The calculation results show that it can suppress flutter effectively and guarantee the slow speed stability,and the system satisfies the stability margins requirements.
