In order to solve the problems that the airborne photoelectric platform in guidance and tracking sys-tem 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.Simula-tion 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.
