Robust H_∞ reconfigurable control of a class of uncertain Delta operator systems with actuator failure

The problem of robust H∞ reconfigurable control for a class of Delta operator systems with parameter uncertainties and actuator failures was discussed. Under the assumption that the outputs of undetectable faulty actuator were arbitrary energy-bounded signals, a sufficient condition for robust stabilization and a method for the design of corresponding controllers were given. The controller could not only stabilize the controlled systems, but also guarantee H?properties against all admissible uncertainties and actuator failure. A numerical example was given to show the effectiveness of the designed method.
