| 摘 要： | 针对半球谐振陀螺平台调平时容易受到各种随机干扰的影响以及为了提高调平的抗干扰能力,基于动态规划方法设计了平台调平系统的随机最优控制算法,使平台调平系统具有极强的抗干扰能力.针对实现中存在的计算量过大问题,采用变量替换法将平台调平系统状态方程转换为完全信息情形,减小了计算量,简化了设计.为了提高调平精度,通过在平台调平控制信号中增加加速度计零位偏置修正量的方式提高了调平精度.初步仿真结果验证了上述方法的有效性.

| Abstract: | The accuracy of leveling system of hemispherical resonator gyro(HRG) inertial guidance platform is easily affected by many stochastic disturbances.The Stochastic optimum control algorithm is designed based on the dynamic programming method to improve the ability of anti-interference of the leveling system,and it makes the leveling system improve the ability of anti-interference greatly.The quite information method of the leveling system state equations is used to solve the problem of calculated capacity by ... |
