Study on Decoupling Control for Cross Coupling of Two-dimension Trajectory Correction Fuze with Crossed Canards

摘要

Several primary coupling factors are analyzed, which lead the cross coupling in correction control with the crossed canard of two-dimension trajectory correction fuze. And the calculational methods of coupling angles are given. For compensating the coupling angle, a gyroscopic pre-angle is presents, which is setup by a micro-electromechanical gyro with three dimensions. And it presents the cascade compensator used in the correction control system to decouple the coupling of the control commands between the double channels. And then it's demonstrated feasibility.
