| Abstract: | The reliable circular disk pole placement design problem of mixed fault model with actuator faiure for a class of uncertain linear systems is discussed.A more practical and general model of actuator failure is presented. Mixed fault model is discrete fault model and continuous fault model coexist in a system, This controller designed to make the system less conservative, A sufficient condition of circular disk pole placement with mixed fault model reliable controller is given. State feedback controller is designed by solving LMI (linear matrix inequality). A simulation example shows the efficiency in a system. |
