摘要
Abstract
To improve dynamic and static performance of flexible gyroscope, the traditional rebalance loop must consider that nutation characteristics have influence on system performance, it is essential to optimize flexible gyroscope' s mathematical model and correction network. Therefore, an accurate flexible gyroscope' s mathematical model are established based on analysis of flexible gyroscope' s motion equation and results of frequency scanning test, this model can really reflect nutation characteristics and only adds a two-order oscillation section to the original engineering simplify model. The loop correction network is designed by the expected correction,and the trap filter correction network is used to eliminate rotor frequency-doubled interference and nutation characteristics. Simulation and test result show that flexible gyroscope' s bandwidth, damping ratio are improved obviously and are closer to bandwidth frequency, the loop noise is effective decrease, dynamic and static performance meet the demands of the new lapping equipment. The technical bottleneck of the application in a certain missile guidance system for this flexible gyroscope is solved.关键词
