Design of a Static Output Feedback H-Infinity Controller for Linear Time-Invariant Systems: an LMI Approach

摘要

This note is concerned with the static output feedback (SOF) H-infinity controller design for linear timeinvariant systems. A sufficient bilinear matrix inequality (BMI) condition is developed for finding a stabilizing static output feedback H-infinity controller. For the first time, a novel cone complementary linearization approach within the context of linear matrix inequalities (LMI) is proposed to investigate the feasibility of the stabilizing controller synthesis along with a minimized H-infinity attenuation rate. The proposed method requires neither any apriori assumption generally made on the input/output matrices nor any application of a coordinate transformation. An example is presented for the application of the proposed scheme.
