In order to realize missile real-time change flight trajectory
three-loop autopilot is setting up. The structure characteristics
autopilot model
and control parameters design method were researched. Firstly
this paper introduced the 11th order three-loop autopilot model. With the principle of systems reduce model order
the 5th order model was deduced. On that basis
open-loop frequency characteristic and closed-loop frequency characteristic were analyzed. The variables of velocity ratio
dynamic pressure ratio and elevator efficiency ratio were leading to correct system nonlinear. And then autopilot gains design method were induced. System flight simulations were done
and result shows that autopilot gains played a good job in the flight trajectory
autopilot satisfied the flight index. 2012 IEEE.

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%

In order to realize the digital of Electromechanical Actuator(EMA) control system
the CAN Bus
which has efficient reliable performance and flexible network modes
works as data interface.The EMA test scheme is designed based on the CAN Bus.First of all
the microcontroller DSP with the CAN Bus works as the core of the EMA control system circuit boards.Then the CAN Bus test network is established with the EMA
Ground Test System and Autopilot computer.The function and self-check of the EMA canbe conveniently tested by the network and the result of the test canbe easily displayed in the PC.Finally
the CAN Bus test network is established with the EMA
the Frequency Characteristics Scanner and etc.The purpose is to test the performance of the EMA.The result of the test can be intuitively showed on the Frequency Characteristics Scanner.In a word
the application of the CAN bus provides a new method to test the EMA and reference to engineering the digital EMA
which has vital significance. 2011 IEEE.
