| 摘 要： | Roll-isolation is an effective way for spinning vehicle to greatly reduce the roll gyro range of strapdown Inertial Navigation System(SINS) and increase the accuracy of inertial navigation.However, during a recent flight test, the roll-isolated control system failure was observed under a large pitch angle(706 h 6 85), which introduces a sharply increase in the roll angular velocity,the saturation of roll gyro and the inertial navigation failure. To address this issue, the governing equation of t...
