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.
Key words: Military aircraft actuation system
