Abstract: The important problem of improving some types of military aircraft survival probability which is the performance of the robust and the quickness of the actuation system is studied. The multivariable nonlinear equations of the actuation system are deduced. After the study of characters of the control system, the fuzzy variable structure control strategy is proposed. Combining the fuzzy theory with the variable structure control method, the controller is designed. The simulation experiments are carried out. The results show that the model and the control strategy put forward can improve the performance of the control system noticeably.
