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%

This article proposes a new fuzzy controller based on information integration. The mathematical model of Linear double inverted pendulum has been studied and estabLished with dynamics analytical method and LQR theory is used to design the optimal Linear inverted pendulum controller
then
the integration technology is used to design the variable parameters self-tuning fuzzy controller. Thereby
the fuzzy controller input variable dimension and the number of fuzzy control rules have been extremely reduced. Two controllers are designed for inverted pendulum system control and the comparison simulation experiments have been done. The results show that the controllers can both reaLize good control
and the fuzzy controller has higher precision
faster response
better stabiLity and robustness. 2011 IEEE.
