To efficiently evaluate the tracking index of theodolite
as well as avoiding influence resulted from higher harmonics when used opto dynamic target and use equivalent sine to evaluate the tracking index
in this paper
we resorted to General Regression Neural Network to do the new research on theodolite tracking accuracy evaluation method. Experimental results indicate that the method realized the equivalent sine to evaluate the tracking index of theodolite and avoided the higher harmonics influence with opto dynamic target. The research in this paper has important value to the engineering practice. (2012) Trans Tech Publications.

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.
