Taken some fixed-wing UAV as the study object
the aircraft movement was broken down into the longitudinal movement and lateral movement according to the linearized small perturbation principle
the longitudinal control law design method was discussed using root locus which belonged to classical control theory. The six degrees of freedom nonlinear model simulation result shows that: the control parameters designed are reasonable
the simulation profile is fully consistent with the setting profile
the control effect of pitch angle loop and altitude loop meets with the indices requirements
the method is mature and reliable
easy to realize in engineering. (2013) Trans Tech Publications

High accuracy is required in surface testing of 90nm nodal point lithography projecting lens. By comparing various aspheric surface testing methods
the structure layout of the compensator is a meniscus positive lens combined with a Plano-convex positive lens. The design results indicate that: primary and high order aberrations are balanced well
we adopt Offner null compensator to test the aspheric surface in the point diffraction interferometer at last. In this paper
MTF exceeds diffraction limit
an Offner compensator is presented on the base of the third order aberration theory to test concave aspheric surface
root-mean-square (RMS) of wave front error /167. The F-number of the system can achieve F/1.64. By the analysis of the process of aspheric surface testing with the designed system
the optical construction parameters of which is determined by introducing equal-quantities spherical aberration to compensate all orders of aspheric coefficients. The field of view of the system is 0.02
a loosen distribution of the tolerance was presented based on the accuracy of measuring apparatus. 2009 SPIE.
