The rotation control technology in the laser gyro strapdown inertial navigation system was studied. The method of realizing closed loop digital control with RLG located in the strapdown inertial navigation system was discussed. The structure of rotation servo system was introduced. The designing method and process of the digital controller were given. The method of implementing digital controllers by means of computer and software flow were demonstrated. The result of simulation and debugging of this system showed that it fullfills the requirment of the strapdown inertial navigation system. It assures the stability of rotation and solves the problem of striking without increasing the volume and cost of the system.
