New synthesis design of reliable robust tracking controllers using LMI

The synthesis and design problem for reliable tracking controller against actuator faults is studied in this paper. A more practical and general model of actuator faults for linear uncertain systems is presented. Sufficient conditions for the existence of a reliable tracking controller are derived. Then the design of a state feedback reliable controller design is accomplished by means of LMI based methodology. Comparison analysis is carried out of control system employing reliable tracking controller and the system without, which demonstrated the necessity of reliable tracking control concept. The example also illustrates the effectiveness of the proposed synthesis
