Abstract :
Based on a [0, σ] model of failures and LMI approach, sufficient conditions for output-feedback systems with integrity are proposed. The dynamic output feedback controllers, which maintain the quadratic stability of closed-loop systems with sensor or actuator failures, can be obtained by solving two matrix inequalities. The effectiveness of this method is demonstrated with a numerical example.
