Satisfactory Fault-tolerant Control for Discrete-time Systems with Multi-index Constraints

For a class of linear discrete-time systems with uncertainties described by unrelated disturbance parameter matrices,the problem of static output feedback satisfactory fault-tolerant control is investigated under actuator failures.Based on a more practical and general model of continuous gain actuator faults,the closed-loop systems are guaranteed by the designed controller to simultaneously meet the required constraints on regional pole index,steady variance index and H_∞ norm index.The consistency of the performance indices mentioned above is also discussed for fault-tolerant control.Meanwhile,the effective static output feedback satisfactory fault-tolerant controller design method is provided.A simulation example shows the validity of the proposed method.
