| 摘 要： | 本文用假想的结构修正法和乃氏判据法对一个三角机翼模型的主动颤振抑制系统进行了控制规律的设计。在精确地确定型态结构参数、电液舵机的传递特性和对传感器位置进行正确选择的基础上,利用简单的、不同的控制规律,使最低的临界颤振速度提高了23％。并与风洞试验结果达到很好的一致。

| Abstract: | By means of the fictitious structural modification method and the Ny-quist criterion concept, control laws of active flutter suppresion systems were designed for a delta wing. Based on accurate determination of the model structural parameters and transfer behavior of the electro-hydraulic actuation systems and on suitable position of the transducers, the lowest critical flutter speed was increased by 23% with different and simple control laws. Good agreement with wind tunnel test results was achieved. |
