摘　　要：研究了一种基于现代控制理论和经典控制理论相结合的舰载武器捷联惯导系统（SINS）动基座对准技术，该方法借助于舰载局部基准的速度和姿态信息，将其通过杆臂效应误差补偿和数据延迟同步后作为基准信息，利用惯性匹配方式进行快速对准，将经典的平台惯导阻尼对准回路引入SINS中，实现了SINS的动基座对准及由快速对准转入值班待机状态时的导航精度保持，避免了SINS长期待机值班后的重新对准。海上动基座对准试验结果表明：该方案不需要舰船作特殊的机动，容易实现，且惯性匹配对准方法提高了SINS方位对准的精确性和快速性，为转入阻尼对准奠定了基础，克服了直接阻尼对准时方位对准时间长、精度低的问题。A novel method of moving base alignment of shipboard weapons SINS that is based on combination of modern control and classical control theory is proposed. The velocity and attitude information of the second-master INS which is used as fiducial references after compensating the level-arm error and processing the data delay. By utilizing the inertial matching method as the fast initial alignment, and introducing the damping technique used in classical platform inertial nav- igation system into the SINS, then the initial alignment for SINS is achieved, the precision of inertial navigation is preserved and also avoids the alignment over again when it is ready on duty after the moving base alignment. The experimental results from sea trial show that it is applicable to moving base alignment for SINS, and it is of adaptability for the accuracy and speed of azimuth fast alignment by using inertial matching method. In additional, it establishes a initial reference with small errors for the damping alignment, and overcomes the defects of the single damping azimuth alignment such as time-consu- ming and low accuracy.
