Symmetry Perturbation and Inverse Problems for Constrained Birkhoffian System;

In this paper,taking the perturbations into account,a method is employed to correct the velocity increment at the first point.

the orbit models, the calculation methods of sub satellite and the coverage judgement which take into account the J 2 perturbations are given first, and then an iterating methods of designing satellite orbit with repeat ground trace is proposed.

Delayed systems, delayed systems with perturbations and uncertain - delayed switched systems are studied using LMI technique.

Based on the fundamental theory of the cable-prestressed steel truss established in paper [1], the inversive iterative perturbation equations which can be used to determine the stiffeness of elements of the prestressed steel truss with elastic supports are put forward by using the principle of matrix perturbation and introducing the concepts of the combined elements and stiffeness factors.
