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.

Autopilot is an important part of aircraft
Under the action of the disturbance torque
for the flight parameters of aircraft Changing in a wide range
the range was about 16km
on the basic of analyzing the typical trajectory
the max height was about 5100m
the trajectory of feature points were selected
the deviation of lateral was about 12m
taking pitch control loop for example
the maximum angle of attack was about 3.6
a sub- PID autopilot was designed using classical control theory
the maximum elevator deflection was less than 5
using single-mode Transient suppression method
the maximum aileron deflection was less than 2
the overload due to control surface transition deflection was avoided when control parameters changing
the maximum roll was less than 5
the verification was done by non-linear simulation. The result showed that: the phase margin of autopilot was greater than 30
the response of overload can accurately track the given overload instruction. An autopilot design method of aircraft of parameter changes in a wide range was provided. 2011 IEEE.
the bandwidth was more than 14rad / s
the settling time was less than 0.7s
the maximum overshoot was 23.3%

The flying qualities of aerocraft was directly effected by the autopilot
for the wide flight envelope aerocraft
on the basic of analyzing the typical trajectory
the three loop autopilots of roll stability
pitch and yaw were designed
using single-mode Transient suppression method
the overload due to control surface transition deflection was avoided when control parameters changing
the verification was done by non-linear simulation. The result showed that: Under the action of the disturbance torque
the maximum roll was less than 5
the range of the aerocraft was from 13.5km to 22.4km
the max height was about 5100m
the max deviation of lateral was about 42m
the maximum elevator deflection was less than 6.5 the control law was applicable within the effective range. An autopilot design method of wide flight envelope aerocraft was provided. 2011 IEEE.
