中文摘要	The optimum method for initial alignment and calibration of the inertial navigation systems is provided based on the stochastic closed loop control configuration and the separability theorem of stochastic linear control systems. The contents include system modeling, design of Kalman filter and the sufficiency and necessary conditions for its stability, optimal control law of stochastic linear control system and sufficiency and necessary conditions for its closed loop stability, design guide line to guarantee the stable convergence of initial alignment and calibration processes, and experimental results of the method applied to initial alignment and calibration for space stable inertial navigation system. The theoretical analysis and experimental results show that the optimum method is realistic and feasible, and its optimization under the condition of admissible control law can be carried out through adjustment of pole location or whole-state update interval of the system, and the navigation accuracy of the system created by optimal closed loop control is remarkably better than that of conventional Kalman filter-open loop control.
