Presents the new independentmodal - space variable structure control for flexible structures with distributed parameter model , which is decoupled into a number of 2 - dimensional subsystems in terms of coordination transmission where , the variable structure control law is designed within the given boundary of structural uncertainty and disturbance , and concludes from simulation results that the algorithm is not only simple so as to accomplish in real time , but also is very robust

On the basis of experimental research , this thesis applies 2 - dimensional non - linear finite element method to the analysis of transient temperature field on the section by means of relatively high precision triangular element of six joints . when the temperature field is analyzed , finite element reseaus are divided in space field and finite difference reseaus are divided in time field , and then the program is compiled . the computing results are in good agreement with the test data
