基于自抗扰控制技术的捷联罗经对准算法

在大失准角条件下，研究了自抗扰捷联罗经对准算法．基于欧拉平台误差角概念建立了适用于自抗扰控制的二阶水平通道状态空间模型．以水平速度误差作为量测实现水平姿态对准，从稳定的水平通道指令角速度中提取方位失准角信息，完成方位自对准．仿真结果表明，该对准算法可较快地实现大失准角的自对准且对准精度与经典罗经对准法相当．

Active disturbance rejection control technique to gyrocompass alignment of SINS

The problems associated with large initial misalignment angles for the so called gyrocompass alignment of strapdown inertial navigation system(SINS) is considered.In this work,the analysis of gyrocompass alignment is approached from active disturbance rejection control(ADRC) theory point of view,which is called ADRC gyrocompass alignment.Based on Euler platform error angles nonlinear error model,the two-order state space model which is applicable to ADRC for level loop alignment is developed.The level loop ...
