Abstract

This paper studies the reliable H₂ output-feedback controller design problem for discrete time linear systems based on the iterative linear matrix inequality (ILMI) approach. The design goal is to find an internally stabilizing output-feedback controller such that the nominal performance (H ₂ norm) of a closed-loop transfer matrix is optimized (minimized). The designed controller also satisfies the reliability constraint (in terms of stability and performance) under control surface impairment fault conditions. The derived matrix inequality condition is less-conservative than existing ILMI based sufficient conditions by adopting free parameters in the characterization to provide extra degrees of freedom in optimizing the guaranteed H₂ performance. Application to a nonlinear F-16 aircraft model with faults illustrates the effectiveness of the proposed approach.
