The thermal control indicators CAE methods of Space optical remote sensor are analyzed in the presented work. We sat up a thermal optical analysis model for space optical remote sensor. By assuming fully covered by in-orbit temperature load
and using the finite element method for thermal deformation analysis
we obtained the optical remote sensor surface deformation and displacement under various thermal loading. Using ZERNIKE polynomial
wave was fitted to obtain ZERNIKE polynomial coefficients which were incorporated into the optical system design. Using CODE V optical calculation software
heat-ray machines under elastic deformation of the system point spread function
transfer function (MTF)
wave front differential (WFE) etc. were calculated. Image quality changes of remote sensors are discussed in variety assumed cases such as temperature loads of quality change. By repeated iteration
critical value of temperature fields meeting the design requirements are obtained for the optical system. Optical indicators were converged to the temperature field indicator
then reasonable indicators of thermal control for remote sensors were obtained. For the thermal control design
this method provided a reliable basis for design. (2011) Trans Tech Publications

In this paper
limit cycle which results from friction during low-velocity servo system has been discussed. First
the piecewise linearization method has been applied to change nonlinear stribeck model to linear model. Second
with analysis of equilibrium property
it is proved the existence of limit cycle and its certain region. The analysis reveals that it is because of stability of equilibrium repeatedly changing results in the limit cycle during low-velocity state. In addition
it also points that the key point to avoid this phenomenon is to keep robust stability of the close-loop system. 2010 IEEE.
