| 摘 要： | 在进行颤振主动抑制的风洞实验中,为了精确可靠地确定机翼主动抑制系统的控制律,有效地达到抑制机翼颤振的目的,必须设计一种其结构和性能都能满足风洞模型的控制面操纵机构,并且必须确定控制面伺服回路的数学模型。本文简单介绍了一种自己设计的用于低速风洞机翼模型的微型气压伺服回路。并介绍了应用频率响应技术测试其动特性和应用最小二乘法由实测频响拟合传递函数的结果。

| Abstract: | For the wind tunnel test of flutter active suppression,in order to determine the system's control law exactly or to suppress flutter effectively,it is necessary to design a kind of control surface actuator of which the structure and performance could satisfy the wind tunnel model.The mathematical model of-it's servo circuit system must be determined.This paper intruduces briefly a miniature air-servo circuit system which was designed by us,together with the measurement of its dynamic characteristic by means of the frequency response and its transfer function synthesis from measured data by using the least square method. |
