According to the context of spacecraft rendezvous system,a non-fragile controller is designed via linear matrix inequality(LMI)method in this thesis.The spacecraft rendezvous system are considered exist variable parameter uncertainty.By using Lyapunov function method fully,the sufficient condition of the controller that is obtained via linear matrix inequality(LMI).It can be solved by the LMI toolbox of Matlab software.Compared with the existing design method of spacecraft rendezvous controller,the control problem of non-fragile are consider that controller exist variable parameter uncertainty.Finally,a numerical experiment shows the validity of the proposed method.
