METHOD OF FUZZY VARIABLE STRUCTURE CONTROL BASED ON THE MILITARY AIRCRAFT ACTUATION SYSTEM

The important problem of improving some types of militaryaircraft 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 carriedout. The results show that the model and the control strategy put forward can improvethe performance of the control system noticeably.
