Popis: An acceleration Feedback(AFB) is introduced to the servo system to improve the dynamic performance of a moving base optoelectronic stability platform.As it is difficult to establish a model for the moving base optoelectronic platform according to a moving object,the proposed acceleration feedback is realized by measuring angle acceleration signals directly.Simulation and analysis indicate that the dynamic stiffness of servo system can be enhanced and the starting and braking performance is improved with the AFB.Experiments show that the capability of resisting friction moment is increased significantly.The capability of resisting periodic disturbance is increased by 9.3db and the overshoot of speed step response is decreased by 4.9%,while the transition process has been greatly improved.The servo system has simpler structure,higher robustness,and shows better universality.
