Design of output feedback controller with robust integrity based on LMI approach

Integrity is an important research orientation of fault-tolerant control,and the study of robust integrity of systems with parameter uncertainties is of great significance in practice.In this paper,sufficient conditions for output feedback systems with robust integrity based on a model of failure and LMI approach are proposed.Dynamic output feedback controllers,which maintain the quadratic stability of closed-loop systems with parameter uncertainties and sensor failures,can be obtained by solving two matrix inequalities.The effectiveness of this method is demonstrated with a numerical example.
