Research on satellite platform vibration compensation technology for space optical communication
The piezo-electric steering control system is used to compensate the vibration of satellite platform.The mathematical model of piezo-electric steering system is built.The adaptive controller based on improved LMS filter algorithm is designed according to this system characteristic.The adaptive delay filter is designed to solve slow convergence speed problem of traditional algorithm.Meanwhile,the adaptive delay filter can also compensate phase delay of control circuit.The adaptive deviation filter is introduced and it effectively compensates the vibration deviation which is low frequency and high amplitude.The experimental results show that the remained errors are μrad,which meets space optical communication requirement and proves that this control scheme is valid and feasible.
