In order to study the effect of backlash nonlinear on resonance frequency of electric actuator transmission system
then
Finally
in the premise of meeting the stability
the dynamic equilibrium equation of transmission system with backlash is established
it makes dynamic simulation analysis for the transmission system based on virtual prototype technology
it establishes balanced equation of dynamics system with backlash
the effect of backlash on system natural frequency and resonance frequency
and the theoretical values and simulation values are compared. Theoretical analysis and simulation results show that the theoretical analysis is basically consistent with simulation results when it is zero backlash
and does some theory research and dynamic analysis of backlash nonlinearity and system natural frequency and resonance frequency. First
and the error of theoretical analysis and simulation results is within 10%. Therefore
according to describing function to theoretically model the backlash nonlinear
it can be concluded that considering the transmission system theoretical analysis of backlash nonlinearity is feasible
the relation between describing function and the amount of backlash and input amplitude is analyzed
and it is much closer to the actual system with instructive significance. 2011 IEEE.

E-O stabilization platform performance is partly decided by gyroscope precision
so it is important to choose a gyroscope with proper accuracy for an E-O stabilization platform. Based on the method of using a gyroscope in practice
gyroscope error model is established. With the gyroscope error model gyroscope accuracy parameters
that is bias repeatability
bias stability
scale factor
scale factor nonlinearity
output noise and bandwidth
are separately analyzed. According to the concretely required performance indices for an E-O platform
means of distribution of gyroscope accuracy parameters is proposed. A MEMS gyroscope is tested to get the parameters. Bias stability of the gyroscope is 0.08 /s while the bandwidth is 60 Hz. Output noise both at zero input and at nonzero input is analyzed by means of PSD to get the result that nonzero output noise is higher than zero output noise. Frequency response result of the gyroscope is dealt by means of correlation analysis. With all the tested result and the method of distribution of gyroscope accuracy parameters
it is clear that how the gyroscope errors works in an E-O servo system. The principle of distribution of gyroscope accuracy parameters is helpful for choosing appropriate gyroscope for an E-O platform. 2011 IEEE.

In order to improve the measuring accuracy of the visible light phase-shifting point diffraction interferometer (PS/PDI) for the extreme ultraviolet lithography (EUVL) aspheric mirrors
the main measuring errors will be discussed in this paper. At first
the elementary configuration and measuring principle of the visible light phase-shifting point diffraction interferometer are introduced briefly
then the different errors which are possible to affect the measuring result are summed up
the errors include PZT phase-shifting error
detector nonlinearity error
detector quantization error
wavelength instability error and intensity instability error of the laser source
vibration error
air refractivity instability error and so on. Through detailed analysis and simulation
the magnitude of these errors can be obtained. By analysing the reasons which cause these errors and the relationship between these errors and interferometer configuration parameters
some methods are put forward to avoid or restrain these errors accordingly.
