中文摘要：
为提高非全姿态惯性平台射前标定精度，增强方案可行性，提出了一种非全姿态惯性平台射前四位置标定方法，用单片机系统构造了平台转角控制与测漂回路，并通过离散变结构控制算法，使系统对于参数不确定性和平台稳定回路误差有了较强的抗干扰能力，平台快速准确地锁定在预设位置，最终标定出九项陀螺仪漂移系数和三个陀螺力矩器系数。仿真结果表明该方法使平台姿态角稳定时间缩短为原来的36％，漂移系数标定相对误差不超过2．4％。
英文摘要：
In order to improve the precision of calibration for the non-full gesture inertial platform before launch, this paper brought forward a method of four poses, designed a system of single chip machine to establish the gesture control and drift measure loop around the platform, adopted the VSC, variable structure control, which made the platform locked at four precise angles speedily, to endow the system with good anti-jamming ability when there are uncertainty of the parameters and error of the platform servo loop, and calibrated nine drift coefficients of the platform and three coefficients of the force moment machine. The result of computer simulation shows that this method decreases the stabilization time of gesture angle to 36% of the former method, while the relative error of the calibration does not exceed 2.4%.
