Robust Guaranteed Cost Satisfactory Fault-Tolerant Control With Regional Poles Constraints

The problem of robust guaranteed cost satisfactory fault-tolerant control with regional poles constraints against actuator failures is investigated for a class of continuous-time systems with uncertainties which do not satisfy matching conditions. The state-feedback controller is designed to guarantee the closed-loop system satisfying the pre-specified regional pole index, H?? Norm-bound constraint on disturbance attenuation and having the quadratic cost performance simultaneously, for all admissible value-bounded uncertainties and possible actuator failures. Thus, the resulting closed-loop system can provide satisfactory stability, transient property, H?? Performance and cost performance despite of possible actuator faults. A simulative example shows the validity of the proposed method.
