In order to guarantee the precise initial flight trajectory  control the missile disturbance of large disturbance torque  three loop adaptive autopilot was researched. The characteristics of the projectile and three loop autopilot instruction formation characteristics were analysed. From equivalent pitching angle of lateral acceleration feedback loop  combined with the instruction of generalized error  autopilot structure was simplified  and three loop autopilot adaptive control law and stability were designed. The test data show that when disturbance torque was 600Nm  the attitude angle generalized error was -4.4. In the time lasted about 15s  late trajectory accuracy was within 1.0.Three loop autopilot adaptive control law was able to control the disturbance of initial trajectory and adapt to dynamic characteristics changes  control system stability. It was the initial trajectory accurate solution method of flight. 2011 IEEE.

In order to reduce the influence of azimuth effect in multi-position strap-down north seeking system  its cause of formation is studied based on the precession principle of the dynamically tuned gyro. A detecting system  composed by true north prism  two Leica theodolites and benchmark prism fixed in the strap-down north seeking system  was designed to calibrate the azimuth effect. By two steps  many measurements are gone on in every position to eliminate the random error. According to the homologous between the error and the position  a sinusoid is made a fit as compensate curve after the error of twelve positions is measured. Then the azimuth effect of the arbitrary position can be corrected by the curve. The experiment result shows that the seeking north standard deviation is only 11.77 after compensation  which is considerably less than the 87.75 without correction. 2008 IEEE.
