摘　　要：针对制导跟踪系统中的机载光电平台在工作时受载机振动和气流扰动引起的宽频随机振动干扰,导致稳定精度下降、图像模糊、跟踪脱靶等问题,提出主被动并联复合减振控制技术。分别采用三环伺服控制和自抗扰位置控制策略,搭建基于音圈电机的单自由度机载光电平台主被动并联复合减振系统。仿真结果表明,主被动复合减振系统可有效降低振动信号对光电平台的影响,并且加入主动减振控制后的系统可以拓宽减振频宽,抑制低频振动信号且信号幅值可在被动减振基础上再次被有效衰减2个量级以上。In order to solve the problems that the airborne photoelectric platform in guidance and tracking system is interfered by the wide-band random vibration caused by the vibration of the carrier and the disturbance of air flow,which leads to the decrease of stability accuracy,fuzzy image and tracking miss and so on,the parallel control technology of active and passive vibration reduction was proposed.Three ring servo control and active disturbance rejection position control strategy were used respectively to build a single degree of freedom airborne photoelectric platform active and passive parallel vibration reduction system based on voice coil motor.Simulation results showed that the active and passive combined damping system could effectively reduce the impact of vibration signals on the photoelectric platform,and the system with active damping control technology can broaden the vibration bandwidth,suppress the low frequency vibration signals,and the signal amplitude can be effectively attenuated by more than 2 orders of magnitude on the basis of passive damping.
