    摘要:

    在各类飞行器飞行的过程中,飞行器载荷会受到不同频段的外扰影响,出现拍照模糊不清楚等问题,建 立主被动一体化隔振平台模型,阐述使用特征模型思想对该平台主动隔振系统进行控制,抑制台面振动。选取超磁 致伸缩作动器作为主动控制元件,建立主被动一体化隔振平台模型;根据力跟踪的平台模型设计了基于位移跟踪的 平台模型;建立位移跟踪隔振平台的特征模型,并将特征模型估计所得的状态变量和黄金分割控制、逻辑微分控制 相结合,对隔振平台的主动隔振控制系统进行控制;通过Simulink 仿真验证了控制器的有效性,并与传统的PID 控 制结果进行对比,证明了该控制器的优越性。

    Abstract:

    During the flight process, the aircraft load is affected by external disturbances in different frequency bands, resulting in problems such as unclear picture of the load. In this paper, a passive-integrated vibration isolation platform model is established for this problem, and how to use the characteristic model idea to control the active vibration isolation system of the platform to suppress the vibration of the table. Firstly, the giant magnetostrictive actuator is selected as the active control component to establish the active-passive integrated vibration isolation platform model. Then the platform model based on displacement tracking is designed according to the platform model of force tracking. Then the characteristic model of displacement tracking vibration isolation platform is established. And the estimated state variables and the characteristic segment based golden section control and logical differential control are combined to control the active vibration isolation control system of the vibration isolation platform. Finally, the effectiveness of the controller designed in this paper is verified by
