A quad-rotor unmanned aerial vehicle is an under-actuated
strong coupled nonlinear system with parameters uncertainty and unknown external aerodynamic disturbance. The trajectory tracking control system with a nested double-loops structure is designed in this paper according to the coupling characteristic between the attitude angles and translational position. A PD control algorithm is proposed in the translational outer-loop to export the desired attitude signals to the attitude inner-loop. An adaptive backstepping control algorithm is designed in the inner-loop with respect to the uncertain rotational inertia and un-modeled disturbance
while in order to reduce the computational complexity the command filtered approach is introduced into the designing procedure. And finally
the numerical simulation results are presented for the trajectory tracking stabilization of a Quad-rotor
which demonstrates the excellent performance of the proposed control system and illustrate its robustness in face of disturbance and uncertain parameters. 2012 IEEE.

Airborne electro-optical stable platform can isolate movement and vibration of the airframe
stabilizes the optic axis of the photoelectic detector
realize the observation and tracking for the object. It has comprehensive application value in army and cicil field. Most of present airborne platforms are analogic control system
digital control system can improve the system general performance
digital control is the development direction of platform systems. In view of the requirements of isolating disturbances and stabilizing optical axis of high-precision photoelectric guidance system
a three-axis stabilized platform system centering on the rate gyro was designed. The disturbance-isolation theory of the stabilized platform was analyzed and the control structure including multiple closed-loops was designed. At last a controller of the servo system based on TMS320F2812 DSP has been designed. Experiment results meet the technical index and precision requirement
and illustrate the practicability and effectiveness of the scheme. 2011 IEEE.

In order to solve the conductive ring module's interference problems
measured the electromagnetic radiation of Power drive module
and used test results analysis the electromagnetic compatibility of the conductive ring
identified and implemented appropriate EMC (electromagnetic compatibility) measures. When optical tracking system working
test equipment can not be fixed. Therefore
from the electromagnetic radiation theory
the paper analyzed the electromagnetic radiation of the power drive module. From it
determine the EMC pre-compliance test method for electromagnetic radiation of power drive module. Based on Test results
calculate the interference voltage of wire in Conductive ring
and then determine the corresponding EMC method. The results show that
when The power drive module Radiate Electromagnetic waves
wires would coupled common mode interference voltage
its frequency is 3MHz
amplitude is about 10V
it would interfered the operation of sensor. By reducing the area of ground loops
used shielded cables
final rule out the interference. 2010 IEEE.
