Reliable circular disk pole placement for linear systems with mixed fault

The reliable circular disk pole placement design problem of mixed fault model with actuator failure for 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.
