A Method in the Alignment of Strapdown Inertial Navigation System Based on Dynamic Programming Theory

Discusses ways of applying the dynamic programming theory in the alignment of strapdown inertial navigation systems (SINS) on the background of land navigation with closed loop control taking the error state as the system feedback and optimizing the control strategy. It shows that starting from the dynamic programming theory, how the stragegy to achieve the alignment can be realized on the condition of quadratic performance index.
