摘要
基于防空导弹的数学模型,根据弹体弹性振动的特性,对抑制其振动的方法和稳定回路设计进行了研究。通过确定频带宽度稳定刚性弹体的姿态运动,采用陷波补偿相位稳定和增益稳定抑制弹性振动以稳定弹性弹体。给出了稳定回路的设计,并比较了不同方法的特点。
According to the characteristics of the elastic vibration of the air defense missile＇s body,the method to suppress the vibration and the design of the stabilizing loop were studied based on the mathematic model of the missile in this paper.The attitude of the rigid body of the missile was stabilized through determining the frequency width.The elastic body of the missile was stabilized through notch compensation phase and gain stabilization to suppress the elastic vibration.The design of the stabilization loop was given out.The characteristics of different ways were compared.
