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.

Restraining the noise
meanwhile
improving the dynamic characteristics of the driving power of piezoelectric pump effectively are the final purposes of doing research on the reciprocating and flexural vibration of the piezoelectric vibrator. However
among many papers regarding piezoelectric pump
there are very few papers about the research on the noise of piezoelectric pump. This is far less than the research on the application of the piezoelectric pump in other fields. In this paper
the research on the flexural vibration deformation and vibration radiation noise of the piezoelectric vibrator are carried out. Firstly
the vibration equations of the piezoelectric vibrator are built and flexural vibration deformation function is deduced. Then
the simplified vibration model of the piezoelectric vibrator is introduced by using vibration theories of micro-area piston. Furthermore
theoretical calculation equations of sound pressure in close noise field and noise contribution equation of fluid in pump are deduced. Finally
a comparison is made between the theoretical calculation value and experimental value
and the contribution quantities of the piezoelectric vibrator and fluid in pump are obtained respectively under different frequencies. The consequence approves that the theory introduced by this research is true. 2006 IEEE.
