On the basis of further research on flexible gyroscope theory

according to the rebalanced loop control principle and lots of theoretical calculation

the diagonalization method is adopted and simplify transfer function model of the flexible gyroscope

and the dynamic decoupling array expression which is approximate and easy to realize is deduced.Neighboring zero pole cancellation method is used in the dynamic decoupling network

thus the decoupling control network which easy to realize on the cirult is constructed

and the effectiveness is verified through simulation.The decoupling network is tested in a certain flexible gyroscope and a few small batch tests is carried out.The result shows that the decoupling control network effectively restrains the coupling quantity of flexible gyroscope in the dynamic process

and the coupling quantity is controlled within 1 %.Bottleneck problems that exists when flexible gyroscope components is applicated in Airborne Wenmiao searching system is solved.
